Question

when very hot liquid is pure in a glass tumbler, the glass tumbler crackes, why does it happens?

Answer 1

BECAUSE..



Glass comes in the insulator class of material which means it is a poor conductor of heat. when you pour a very hot liquid into a thick tumbler what happens is, the surface of glass that comes in contact with the hot liquid heats up and expands as per its coefficient of thermal expansion, while the outer layer still remain cold and does not expands...

Hope this helps you out!!

Question: When very hot liquid is pure in a glass tumbler, the glass tumbler cracks, why does it happens?

Solution: When you pour a very hot liquid into a thick tumbler what happens is, the surface of glass that comes in contact with the hot liquid heats up and expands, while the outer layer still remain cold and does not expands (because glass is a poor conductor and does not carry heat to the outer layers). Due to this uneven expansion it cracks.
