146632 An air bubble of volume ' $V_{1}$ ' is at the bottom of a lake of depth ' $d$ ', where the temperature is $T_{1}$. The bubble rises to the surface, which is at a temperature of $T_{2}$. Assuming that the bubble's air is at the same temperature as that of surrounding water, the volume of the bubble at the surface is (Let $P_{0}$ is the atmospheric pressure and $P_{1}$ is the pressure at $T_{1}$ )

146633 Two identical glass spheres filled with air are connected by a horizontal glass tube the glass tube contains a pellet of mercury at its midpoint. Air in one sphere is at $0^{\circ} \mathrm{C}$ and the other is at $20^{\circ} \mathrm{C}$.
