Two identical glass spheres filled with air are connected by a thin horizontal glass tube. The glass tube contains a pellet of mercury at its mid-point. Air in one sphere is at 0°C and the other at 20°C. If the temperature of both vessels is increased by 10°C, then neglecting the expansion of the bulbs and the tube
