(C) The coefficient of cubical expansion of the vessel $(\gamma_v)$ is related to its coefficient of linear expansion $(\alpha)$ by the formula $\gamma_v = 3\alpha$. Given that $\alpha = \frac{\gamma}{3}$,we have $\gamma_v = 3 	imes (\frac{\gamma}{3}) = \gamma$. Since the coefficient of cubical expansion of the liquid $(\gamma_l = \gamma)$ is equal to the coefficient of cubical expansion of the vessel $(\gamma_v = \gamma)$,both the liquid and the vessel expand by the same volume fraction for a given change in temperature. Therefore,the level of the liquid in the vessel will remain almost the same.

$A$ liquid having a coefficient of cubical expansion $\gamma$ is kept in a copper vessel having a coefficient of linear expansion $\alpha = \frac{\gamma}{3}$. If heat is supplied to the vessel,the original level of the liquid in the vessel will
