Q. A metallic container is completely filled with liquid. The coefficient of linear expansion of the metal is per and the coefficient of cubical expansion of the liquid is per . On heating the vessel :

Thermal Properties of Matter Report Error

A

The liquid will overflow

B

The level of the liquid will fall

C

The level of the liquid will remain unchanged

D

The level of liquid will rise or fall depending on the nature of the metal and of the liquid

Solution:

Coefficient of cubical expansion of container,

Coefficient of cubical expansion of liquid,

Thus, both container and liquid will expand to same extent and level of liquid remain unchanged.
