On heating a liquid of coefficient of cubical expansion $\gamma $ in a container having coefficient of linear expansion $\gamma /3,$ the level of liquid in the container will

A

Fall

B

Rise

C

Remain unchanged

D

It is difficult to say

Solution

If linear expansion is $\alpha,$ then $\gamma=3 \alpha$

Here, $\alpha=\frac{\gamma}{3}$ so $\gamma^{\prime}=3 \times \frac{\gamma}{3}$

Thus, $\gamma^{\prime}=\gamma$

Hence, volume expansion remain unchanged.
