Solution

The correct option is C $W_{2} > W_{1}$
Given,

$γ_{s} < γ_{L}$

The coefficient of expansion of solid is less than the coefficient of expansion of the liquid.

Because of this, the weight of displaced liquid will decrease as temperature increase. Therefore buoyancy force decrease

Hence, the apparent weight will increase as the temperature increase, $W_{1} < W_{2}$
