VT♑︎ :
So does it expand outward or inward

Gabriel Roux :
Why would it get smaller

Niklas :
good explanation 👌 😂 intuitively it feels like it should expand inwards even if I know it doesn't

Metal is put together in a unique way. Every atom in the metal shares electrons to a «electron-skye» wich makes metal low resistant and that means that metal also transfers heat and expand equally.

metal? is it solid?

Gabbe 🇸🇪 :
If the sheet is infinite in size, would the hole still get bigger though? And if so, why would atoms want to be closer together when they get heated?

Dont they also freeze the metal part that goes in

Thank you for teaching me about hole.

It depends on hole size vs wall thickness and the heat distribution . Usually the hole gets bigger, but in some cases it gets smaller. This is very important when doing heat treatments

shoehorn :
i alway wonder...does the hole get bigger or smaller....think if i had a square bar, If I heat it, it gets bigger. now if I make the bar into a circle...does the hole gets bigger or smaller? its gets bigger as the bar also grows in length more than width, making the hole bigger

Good videos and you are wonderful. But it still drives me crazy that today people sell basic physics facts that everyone learns around 12yo, and just act like it's world changing big ideas

already knew this because in my engineering class some kid trapped is finger in a metal sheet and it shrunk
