medium

A liquid with coefficient of volume expansion $\gamma$ is filled in a container of a material having the coefficient of linear expansion $\alpha$. If the liquid overflows on heating, then

A

$\gamma = 3 \alpha$

B

$\gamma > 3 \alpha$

C

$\gamma < 3 \alpha$

D

$\gamma > 3 \alpha^3$

Solution

Volumetric coefficient of expansion of material is $3 a$

As the system is heated liquid started flowing out of box, it means volumetric coefficient of expansion of liquid is greater then of the container.

$\mathrm{So}, \gamma>3 a$
