Question

A hot glass craaks when placed under cold water? Explain​

Answer 1

Answer:

So when a hot glass is placed in cold water it expands due to conduction of heat. But the heat doesn't flow evenly in the glass. Hence, the expansion happens unevenly. So due to unven expansion, the glass cracks.

Answer 2

Answer:

A nonconductive material cannot conduct heat evenly throughout it's body. So when a hot glass is placed in cold water it expands due to conduction of heat. But the heat doesn't flow evenly in the glass. So due to unven expansion, the glass cracks
