21:49 gold Smith uses the outer layer part to melt gold and silver because metal needs high temperature to melt.
Yes, right
Correct
Truu
There r three layers in candle zone and the outermost layer is the hottest part that’s why gold smith uses it to burn metal
Ma'am in types of combustion there is also a slow combustion it is a form of combustion which takes place very slowly and at low temperature example- cellular respiration
But the topic of slow combustion is not in the book of class eight ncert
Like rusting too
Thank you Ma'am
You are a wonderful teacher !
Your way of explanation is WONDERFUL , FUN & EASY.......I was struggling to understand some chapters...But now I get !
I really appreciate your way of teaching ❤️
Again THANK YOU SO MUCH !
🥰
Yes Ma'am
Yes ma'am
Mam blacksmith use the outermost part of the flame to melt gold and silver because it is the hottest part of flame.
Yes
Yup
Blacksmith ❌
Goldsmith ✔️
Mam it's very helpful but there is a doubt can we also use sand as a fire controler. As I see in petrol pump their are bucket which contains sand
yessss you are right we can also use sand as fire extinguisher
13:41
Mam water controls the flame by increasing the ignition temperature,and you told that it reduces the ignition temperature. because if it reduces the ignition temperature it means it will catch fire more quickly.
It was a correction
Ur way of explanation is very very impressive ❤
Mam the hottest zone of the 🕯🕯🕯your teaching is brilliant superb
Mam your explanation is so good my 9 friends all batch mates of my class has subscribed your channel I think your channel is more good than vedanta , byjus, unacdadmy

Hi.. even i love magnet brains but i also love every other channel so please don't comment like this😢😢😢😢🙏🙏
Good evening ma’am.does the burning of tissue paper come under spontaneous combustion or rapid combustion
Thank you for your question! Spontaneous combustion is when a material ignites without an external heat source, while rapid combustion is when a material ignites very quickly with an external heat source. Tissue paper ignites quickly, so it would be considered rapid combustion.
Rapid combustion
Goldsmiths blow the outermost zone of a flame with a metallic blow pipe for melting gold and silver

Question: The ignition temperature of wood is high right? That's why it takes time to reach a particular temperature to burn.. but Ma'am said its low..
She said it by mistake maybe
The goldsmith use the outermost zone of the flame as it the hottest part of the flame and metal can be moulded in required shape
Note : Rusting isn't a combustion reaction but oxidation reaction.
It's very helpful and I always recommend magnet brains for science. Thank you ma'am for this amazing lecture ❤️

You taught really nicely 😊. Thank you. But one thing in the activity for the structure of the flame I think the tube should be near the innermost zone because the unburnt particles are present there also they mentioned dark inner zone. 😀 Thank you for reading. 😁
