Give reason: Hot water when poured in glass beaker, it cracks.

Answer»

1. When hot water is poured in a glass beaker the inner surface of the glass expends on heating.

2. Since glass is a bad conductor of heat, the heat from inside does not reach the outside surface so quickly.

3. Hence the outer surface does not expand thereby causing a crack in the glass.
