It's still losing its energy through infrared and visible wavelengths as well as other types of radiation no matter what. Just like the sun in space. This is why the inside of a thermos has a shiny coating, to reflect the radiation back to the contents.
Wow, now I know.
@@Ingi-Natura-Renovatur-Integra The sun can't necessarily a giant flaming ball.
@@Ingi-Natura-Renovatur-Integra why do you disagree
@@Ingi-Natura-Renovatur-Integra Flames need fire so it cant be in space. The sun is not on fire, its radiating, think of it more like a lightbulb. Its more of that than actual fire.(srry if your comment was a joke)
Edit: Sleep Deprived me put Fire needs flames. Fire needs oxygen to be alive so the sun isnt on fire, its glowing from the energy of nuclear fission(Idk if this is the right word).
@@Ingi-Natura-Renovatur-Integra Wrong, fire can be in space as long it has oxygen and fuel that's how rockets work, about the sun you forget that gravity exists and this creates an atmosphere, so no the surface of the sun it's not exposed to the vacuum of space
Radiating heat in a vaccum, isnt that what the sun does ?
Yup
It's called the greenhouse effect. Light hits the earth and the energy turns into heat
The earth does that too.
That is the reason why it gets cold at nigth.
@@diceydie8502 yeah light turns to earth and earth turns to heat
@@twisty8005 So it's not heat going through space
I love how everyone seems to forget that the ball is resting on some nails. It's not floating in mid-ai... in mid-vacuum. So even if it didn't radiate heat, it would eventually reach equilibrium through conduction. I do believe the radiative heat transfer is faster in this specific case than the conductive heat transfer. Like _way_ faster. But it's not negligible long-term.
Reduced to the actual cause of the 'heat' - which is insanely intense motion of the particles (the constituent parts of the atoms) of the metal ball --
-- all you have to do to answer the question "how will the metal ball lose its heat?"
So another way to ask the same question is "what will gradually slow the motions (aka the kinetic energy) of the particles in the metal ball?"
1) the ball is 'transmitting' electromagnetic waves - and each electromagnetic wave the ball produces carries off energy from the moving particles in the ball. The electromagnetic waves that the ball is 'transmitting' are in the infrared and the visible light frequency ranges
2) the ball is held by a mounting 'seat' on a wood platform. As the ball's particles move around, they are in physical contact with the particles that make up the mounting seat. The motion of the ball's particles transfer motion to the particles of the mount.
ANSWER: to prevent the ball from losing 'heat' (aka intense motion of its particles) - you'd have to somehow stop its electromagnetic 'transmissions' and somehow cause it to 'float' and not touch anything.

Was hoping you would compare the time it took to cool to room temp as compared to a none-vacume.
Neuromancer yes I thought that’s what he was going to do. Something to compare his results to 🧐
He said it took 2 mins when it was in air. You would’ve know that if you paid attention.
He stated that it took about 2 minutes to cool in air as a written foot note, though, he didn't say it.
@@SpiritofPoison Yeah, but we don't know if he meant in the vacuum chamber, or sitting out in air.
@@DANGJOS The footnote says "Off camera **with air** it took about 2 min to dim"
Yeah, that’s a pretty poor representation of a human hand vs red hot metal imo. Speaking as someone who has worked with 2000+F furnaces and has been burnt many times over the years. If it's hot enough, it will cut through flesh like a hot knife through butter. Especially skin, it's instantly gone. I have a nasty, thick scar on my upper arm from when I accidentally bumped into a ceramic plate that had just come out of the furnace. The furnaces typically have coolers on them that use liquid nitrogen like a cars radiator, except instead of coolant pumping through the system it's liquid nitrogen. But the cooler wasn't functioning correctly that day so everything coming out was extremely hot, actually 2000F is kinda on the lower end of the temperature we use in our furnaces, some of them get much hotter, although I don't know exactly how hot since I don't work on those myself. I only made contact with that ceramic plate for an instant and it cut right down to fatty tissue. Even if the coolers are working properly, anything coming out of the furnace is still hot enough to give you third degree burns for at least a few minutes. I have seen situations where furnaces were emptied with no cooling whatsoever, and being even within 15 feet of the exit of that furnace would have you dripping with sweat.
Yes. Should have used pork belly or such
Mmm the smell
Liquid nitrogen (or even water) for cooling furnaces -- wouldn't that cause cracking due to extreme thermal stress?
@@saeer5038 😆 yeah, like burning a steak
@@Lucius_Chiaraviglio it goes through several cooling zones with the last one being the most significant reduction. Yes, it can cause cracking if it’s not done correctly. The parts sit on a belt that moves very slowly, so it’s not a rapid process. The parts also typically sit on carbon, carbon fiber, or ceramic plates that kinda act like heat sinks and help to draw heat from the parts evenly. I mean, when we do the induction heat treat operation we use electricity to heat up coils red hot and basically instantly heat treat a part then immediately quench the part with coolant. I’ve never seen cracking being an issue with induction heat treat.
Actually incorrect mixture in the furnaces atmosphere causes the most significant defects (Assuming temperatures are correct). Parts will come out warped, cracked, or discolored. They usually come out your standard grey/silver color, but get too much oxygen in there and they’ll come out blue or even yellowish.
I don’t really work with the furnaces much anymore tbh, but I’ve just been doing it for so long I know quite a bit about it. My dad was a furnace technician, a veritable fountain of knowledge, unfortunately he passed a few years back.
It would be very interesting to have another ball with the same initial temperature outside the vacuum chamber to notice the difference on the coiling time,
What I learned from this video:
Don't give a RHNB to somebody to hold, they will keep dropping it :-o
nah its bc its too hot, humans cant handle much heat.
@@Kuino r/whooosh
Drop it like it’s hot
worlds first fake game of hot hands. lol
As a result a potential loss of the ball might occurr.
When youtube becomes your search engine.
Javale McGee honestly though
Earth is not FLAT its OBLATE SPHEROID
And the NSA is like: "Why do you want to learn about vacuum and hot balls? 🤨 You're trying to vandalize the universe, aren't you
?! ... Yeah, you got busted! 😏"
ok fbi
I swear
It's nice to remember that these vacuum machines can't even remotely reach full vacuum, the power is very small, there are many experiments that you can't do with them. An old mercury-based vacuum chamber would be needed, and yet it still has mercury vapors. So this experiment unfortunately failed in the question because there is still a lot of material to do the heat dissipation.
There are other methods to gererate a good vacuum then mercury based pumps. But the one in the video was clearly not sufficient to go below 20 mbar.
The reason the ball was able to cool down is the same reason the sun is able to heat up planets and other celestial bodies through the vacuum of space. This experiment successfully demonstrates radiation.
@@99mage99 The formula for heat loss by radiation is known, and it is much slower than heat loss by contact. Scientifically there really is nothing to say, it would eventually lose heat through radiation. But this was not demonstrated by the experiment, where heat was still lost through contact and not only through radiation. The concept pointed out by him is valid, the experiment is flawed.
You're so good at explaining things. I love to learn but a lot of people who teach seem to wanna flex how many words and ideas they know rather than walk through and teach in a way anybody can understand. If I had a science teacher like you back in the day I might be something right now lol
k@@RepentandbelieveinJesusChrist5
The answer is in the title. "Red Hot". I.e. radiating energy in the form of EM waves in the visible spectrum.
Much more energy is being radiated as non visable infrared. Also convection and conduction are a much bigger factor in the ball loosing heat.
Jared Freedman
L
@@jaredf6205 Much bigger? Are you sure about that? I think people underestimate how big an effect radiative cooling can have.
Did these smart people at least skip to the end to see that it was explained in the video? Funny how they still felt necessary to explain it again.
@@jaredf6205
There is no convection in a vacuum. And on the observed time scale, as the presenter in the video correctly explained, the conduction was negligible. The ball cooled through radiative heat loss in this case.
Would be cool to see this one done again, this time with 2 spheres and with precise temperature measures on both: one in the vacuum, one in the open; would be interesting to see how different it goes, specially to see if the heat loss difference would be noticeable.
Yes definitely
It will be noticeable, the main difference is that on vacuum the loss happens by irradiation of light and other emissions!
In the air it would have also happen the transfer of heat.... Maybe is just a few seconds but for sure it will be faster!
Interesting anyway to see those tests!
Yes
@@anthonyaubert4074 It would also be faster out in the room because the walls is the vacuum chamber would keep it warm longer.
@@DANGJOS Liquid can only exist under atmospheric pressure. So in a vacuum, any ice melted into water would boil, dropping the temperature of the water until it re-froze the water back into ice. Also, any water vapor, which would hold the bulk of the heat, would be pulled out of the chamber. Water also has far more capacity to hold heat energy than air, or even metal. A complication would be that boiling water that freezes in a vacuum chamber has a tendency to shatter.
It loses some heat through conduction into the screws. The rest is radiated.
I love how you ask these questions you know the answer to. Much love from Turkey!
I already knew about the fact that the ball would just radiate the heat even in the vacuum but I still wanted to watch it because it's awesome to see your videos
Same thing when I saw the video title, but I still clicked it
Too arrogant
I think most people did,but didn't feel it necessary to tell everyone about it.
Cz sun can radiate in vacuum so will the nickel ball😂
Through infrared radiation
Try any object that vibrates (guitar string, a cymbal, etc etc) and put it in a vacuum chamber and see if it will stop vibrating.
It will
so vibrations dont go through our galaxy
It will stop
It'll stop because the tension on the string is acting upon it to bring it to a stop. But while it's in the vacuum chamber, it would be difficult to hear
It would stop
"no medium to transfer heat"
*laughs in photons*
it’s almost like you didn’t watch the entire video
I have never grasped the three methods of heat transfer more clearly than in this moment. Even though you barely used any words, the descriptions made the most sense of any explanation I have heard.
The heat will radiate through vaccum. Radiation can travel through vaccum.
Got to love thermodynamics
Yeah, expected to last longer though. Seeing radiation is the weakest form of heat transference.
@Sacred Icon explain hypothesis
@Sacred Icon but we can expect already proven results. The thing is don't believe something blindly, it's not science.
@Sacred Icon yeah strong belief based on evidence. Blind belief based on just belief and compel a person not to change belief. But expectation can go wrong and the person can understand it and change his KNOLEDGE accordingly ,that is science. Understand the difference.

To verify results, you should also check how long a red hot nickle ball takes to cool down in normal atmosphere. An any difference would prove that heat is propelled via light.

no, it already proves that heat is transferred via radiation. with your mechanism, any difference would prove that heat is transferred via air touching the ball.

love the way you clean your crucible.
I love how you see this , and yet think there is a core of the esrth that never cools
I feel it's worth pointing out that heat is most effectively dissipated in the form of infrared light, which would not be affected by a vacuum
Most effectively?
Idk about that chief, I get way more burned by touching red hot steel than I do from standing next to it.
Not most effectively. Radiation is the slowest form of heat transfer for a given temperature difference. However it is the longest ranged method, and the one that works well throughout 99.999999999999% of the universe
Also explains why you instantly feel the pyrotechnics at concerts, even if it is like 30+ meters away 👍
When the bombs blew up over Japan, powerful radiation from the blast propagated at the speed of light, meaning if you had a line of sight to the explosion, you were instantly affected, well before the shock wave or explosion materials hit.
Tom Haflinger got so dark so fast. From concerts to mass killings
@@THEDnARACER yeah, I could have picked something cheerier. How about, "That's why when you sit around a campfire, you're better off sitting upwind from it. The wind blows the smoke away from you, and the radiating heat isn't affected by air currents anyway."

you know what?... I've got a test for tomorrow of thermal energy and this was exactly what I want 🔥

This is a good example of heat insulation. As there are much less particles of gas in the vacuum chamber, less gas particles will be colliding with the hot particles in the nickel ball. Meaning there is not much to conduct heat from he ball
So, what you wanted was a reminder that, to no one's surprise, heat can move through a vacuum, thus proving that the sun is not actually a lie created by the Illuminati? The pointlessness of this video is staggering to me...
@@weissxritter Still people who didn't pass age 6 ?

THANK YOU FOR EXAPLAINING HOW HEATING WORKS !!!
Brilliant demo...
I remember when I was in high school, and had my fingerprints burned off... I was in welding, and someone didn't properly take care of a piece of 1/2" scrap that they welded. I guess they finished with it just before class was over, and during cleanup, I saw it on the table next to the scrap bin. Went to pick it up (stupid me without gloves) to toss it into the scrap bin, and it came up not even an inch off of the table, before sliding out of my fingertips. The way the ball reacted when placed on the silicone hand just reminded me of that.
Damn. Wow. Any estimate of how hot it was? That's crazy!
Have you ever been to jail? If so, how did the cops react to you missing your fingerprints?
@@ThePrufessa No idea how hot it was. It wasn't glowing anymore, but was still hot enough for it to just slide out of my fingertips. It wasn't a severe enough burn that my fingerprints didn't come back. They eventually did, but were smooth for a while after it happened.
@@ufninuyasha oh wow. That's amazing that they actually grew back! Thank you for replying!
@@ThePrufessa welding makes metal red hot. So assuming its AT LEAST 150+ °C

70+ °C can already cause burn scars on human skin.
I have a 1 by 1 inch but on my left wrist from 3 weeks ago when i had a small accident with 400°C hot metal. So burning your finger prints off. Probably between 150 and 250°C
If the metal wasn't glowing any ore it cud be still about 100°C i guess.

Cairn heat is lost through radiation and not through convection and conduction as radiation do not need a medium to transfer heat
it is the comment that i am looking for.
What happen if your vacuum chamber build with one way mirror wall, so what i mean here is from the inside perspective (the ball position) its gonna be a normal mirror, but on the outside we see the normal glass through looking (we can see the inside). So will the ball heat doesnt lose energy because its reflect back, but at the same time we can look to the inside?
Your nervous system doesn't even feels pain, feels like a little freezing ball but yea, stains looks similar and bubbling later.
Im wondering if you will install perfect mirrors in the vacuum so it will recover the power lost on photon emmission. I think it will cool down slower
red drawf star!
Yep. And thanks to the massive difference in surface area to volume ratio, the red dwarf star will take an astronomically (see what I did there?) longer time to cool
Actually it's brown dwarf star, because there no nuclear fusion in it.
Cool experiment. Something to try if you do this again. Use magnetic levitation for the ball so it doesn't conduct through the nail. Also cover the box with a mirror to reflect back any heat.
Also, aim a some kind of temperature sensor at it. It would be obvious it’s losing heat but where would be interesting.
The ball can't be magnetised at high temperature, and some kind of electrically induced magnetism would be very difficult to set up. Perhaps possible, but technically very challenging.
A good idea for softening metal such as steel. Put it in an infra red reflective coated vacuum chamber and you should get a very effective annealing chamber
Blacksmiths just use sand thats preheated by the furnace. Then it slowly cools. Keeps the swords from bending or warping as much.
Do you know what are the good heating elements for vacuum drying? It seems the vacuum drying ovens use FIR (far-infrared) heating elements made of carbon, but do other types of heating elements work, too? Wouldn't they overheat in vacuum? What about simple resistance wires (e.g. kanthal) - would they work?
It started looking like one of the suns at tattoinne at 2:33
Can you do an experiment on youngs double slit experiment and Lenards observation
What fascinated me when i first heard a detailed explanation of heat transfer by radiation, was that every body emits and receives radiation. The hot body emits, but also the cold body emits. And both receive each other's emissions. The key is that the body at higher temperature, it emits more radiation, and the one at cold temperatures, it emits less energy radiation. Therefore they exchange heat back n forth, both directions, but the net effect is heat transfer from hot body to cold one.

"Uh yeah, heat transfers without a medium. Heat does not equal sound."
Geopuzzler thermoses use vacuums..... how about in an insulated string and once it loses its electromagnetic light radiation it should stay hot for like 3 days just like a coffee thermos does with hot coffee but at 800 Degrees it would stay hot alot longr

I wonder if the transfer of energy to the air in the vacuum allowed it to cool since you were moving the heated air away with the vacuum, similar to how a heatsink works
You can freeze water in warm ambient temperatures at night by exposing it to space on a clear night.
That would be a fun experiment to watch you try.
I think you're underestimating the heat sink properties of the stand its sitting on. Would you be able to magnetically levitate the ball and redo the experiment? That would be AWESOME.
Ferromagnetic objects lose their magnetic properties when this hot.

I had a similar thought yesterday, if you put water in a vacuum and then try freezing it, would it take more than to freeze or will it freeze normally? The white stuff inside ice is air trapped while the water freezes so putting the water in a vacuum would give you a clear block of ice?

@@CanadaBud23 then might I ask how does he get it to full vacuum to begin with? 🤔 at least for a short time, that air has to get pulled out somehow
Edit: that’s what I was meaning by the pulling, not the vacuum itself, but the obtaining of said vacuum
@@MysteryBatz You're not ever pulling a vacuum, that's a figure of speech. Pumps "push" the atmosphere out. The air trying to get in is the outside atmosphere pushing its way back in.
The ball is like the villain who blocks multiple attacks from the heroes while loading up his power
Radiant heat
When I was 8n HVAC school I wondered about this too
I wasn’t paying attention and nearly had a heart attack when I looked back and saw him put the ball on that hand 🤣🤣🤣🤣
Unless the valve on the vacuum pump was closed toward the end, the pump was pulling heat out as well as air.
The energy crisis solved!! Good work!!!
YT is telepathic now! I thought of this very thing yesterday...
This is not the first time.
Next, can you see if gallium will cool from a liquid to a solid in a vacuum chamber with no air?
Why not? It's the same thing, he just explained to you.
Without doing the experiment, I can tell you yes it will eventually cool down, even though there is a vacuum the ball is still shedding energy by infrared radiation(light).
Light does not require a medium to propagate through, it will cool until it reaches equilibrium with the radiation entering the chamber from the room.
Actually if untouched or reheated, it will keep cooling until the heat death of the universe since everything above absolute zero is losing heat, even the CMB.
It's transfering the heat to the screws holding it then to the playform.
Also, light can move through vacuum.
Yes you pulled out the space inbetween the gas too💜
There was still a medium onley more negative and less to circle around💜 so the boll is able to breaghe and leak out and these start exelerating thame selfs💜
Bit was the colling faster in the vacume ???🙏🙏🙏👀👀🌹
Thank you and oll😋🎁
Oll injoy beïng🙏👐🙌🙌🌈🍀
What the heck is this
I was learning about heat transforming(those 3 types) 2 month ago xD
I learned about them a week ago, what a coincidence
@@retiredchannel pa čuj...dobio sam 5 iz odgovaranja - dobro sam naucio hahha
@@dnetne5508 lepo
I've read those topic at 6th class in 7th Chapter(Name-Energy transformation)
I can't stop thinking about the pink season music when he says "red hot nickel ball" anyone else?
What if you lined the inside of the box with reflective surface, would it only then be loosing heat at the base?
You should try tje same experiment but with aluminium foul insulation in the vacuum chamber to reflect the heat back to the ball. It'll be interesting to see the time this way
