Question

On heating a liquid of coefficient of cubical expansion ${}^{\prime }{\alpha }^{\prime }$ in a container having coefficient of linear expansion on ${}^{\prime }\alpha /3^{\prime }$, the level of liquid in the container will:

• A. Rise
• B. Fall
• C. Will remain almost stationary
• D. It is difficult to say

Answer 1

Answer: (C)

Will remain almost stationary

Cubical expansion of liquid is 3 times its linear expansion.

$\beta =3\frac{\alpha }{3}=\alpha$

The volume expansion of both liquid and container are same, so the level will remain same.
