Figure shows two rigid vessels A and B, each of volume 200cm³, containing an ideal gas (C_v = 12.5JK^-1mol^-1). The vessels are connected to a manometer tube containing mercury. The pressure in both the vessels is 75cm of mercury and the temperature is 300K.

Find the number of moles of the gas in each vessel.
5.0J of heat is supplied to the gas in vessel A and 10J to the gas in vessel B. Assuming there's no appreciable transfer of heat from A to B, calculate the difference in the heights of mercury in the two sides of the manometer. Gas constant, R = 8.3JK^-1mol^-1.

Water leaks out from an open tank through a hole of area 2mm² in the bottom. Suppose water is filled up to a height of 80cm and the area of cross-section of the tank is 0.4m². The pressure at the open surface and at the hole are equal to the atmospheric pressure. Neglect the small velocity of the water near the open surface in the tank.

Find the initial speed of water coming out of the hole.
Find the speed of water coming out when half of water has leaked out.
