- This video illustrates how strong of a force air pressure can cause when a vacuum is created inside a pair of hemispheres such that they can't even be separated, similar to the Magdeburg hemispheres experiment performed in 1654.
You need a medal 🏅
This video is so easy to follow and helped me understand suction properties and air pressure. Thanks!
Amazing, holding my hand! 🤝
superb explanation
thank you for this video
This is a good teaching
Thanks for making this video 😁
Awesome, thank you.
Is there an experiment that shows a pressure system existing within a vacuum with no physical barrier separating the two?
You are good
Can we launch projectiles with the help of vacuum
i am curious. when vacuum is in a chamber like that with a gauge, is it measured in negative pascals or positive pascal? if not why doesn't vacuum get measured as negative presser with a (-) negative symbol attached to its value?
From what I understand, the vacuum is measured in positive pascals and has a value close to 0. What’s keeping the two spheres connected is not a “suction” from the inside, but atmospheric pressure from the outside, as discussed at the beginning of the video.
Thank you for showing us that a vacuum can’t exist next to gas pressure... they both need there own containers
Yep! That's why globe earth is a lie. There's many more reasons but this is one even science cant refute, but they still do with "gravity".
How did the air leave the vacuum?
JSSTyger it doesn’t... that is the point... in order for us to have pressure on earth, it needs to be contained
@@silverumbrella8058 you can suck air out of a bottle through a straw and create a vacuum. The air leaves the bottle because of a force pulling it out. You are essentially replicating exactly what gravity has been said to do for 350 years. It pulls...and it is a constant pull. Everything tends toward the Earth, including air. Like a strong magnet.
JSSTyger you are one confused person... sorry for you... the earth is flat ... there is no need for gravity... things fall down or go up because of the density of the object
so how is our atmosphere not dissipating into the vacuum?
on earth we cannot create two opposing pressure systems with out a barrier seperating them?
I:E a negative pressure system against a pressuerised system
in reality whichever is smaller would equalibrate into the larger system?
and if there is a vacuum it would be vast in relation to our atmosphere
a 330 year old theory does not allow us to demonstrate this practically
not flat
can i suggest you watch the video above before you tell me our atmosphere isn't pressurised
are you claiming the teacher/physicist in the video is liar as well??
and still you quote theory's to argue against facts
you truly are delusional
not flat
yes to all
but citing variances in pressure just means its a pressurised system
that incorporates pressure differences
so all you have basically done is prove we live in a pressurised system??
i couldnt have put it better myself thank you
Clearly you cant have a pressurized system next to a vacuum
Air pressure gradually decrease with altitude. So with higher altitude you are slowly closer and closer to the "ideal" vacuum.
Same effect you can observe in weather forecast, you can see that in two cities in same country is different air pressure without container between them.
To have pressure gradient is possible in reality. The force which make air pressure on Earth is gravity.
@@hera9191 I sure hope you don't believe the unverifiable nonsense you dribbled
The right word feels like it should be hemispheres instead of spheres.
Thank you for explaining that a rocket cannot work in space. .We kinda suspected it anyway , co of the rubbish moon landing film footage.
Why do you think that rocket cannot work in space? It works even better in vacuum because it caries its own oxidizer.
@@hera9191 No. A rocket needs pressure behind it to force it forwards. That is the whole point of a rocket. It needs pressure. And you cannot create pressure in a vacuum.
@@boptah7489 1) "A rocket needs pressure behind it": That is not true, rocket engine use action-reaction law (Newton's third law) en.wikipedia.org/wiki/Reaction_engine . Same principe as "conservation of momentum", you can make your own experiment with billiard balls. en.wikipedia.org/wiki/Momentum#Conservation
2) "you cannot create pressure in a vacuum": not relevant but also not true, you can easy create pressure for example with burning rocket fuel
