Mr Chua experimented on water movement within a rigid tank. The rigid tank is divided into two equal parts by a partition. Initially, one side of the tank contains 5.0 kg of water at 200 kPa and 25ºC, and the other side is empty. The partition is then removed, and the water expands into the entire tank. The water is allowed to exchange heat with its surroundings until the temperature in the tank returns to the initial value of 25ºC. Determine: a) the volume of the tank. b) the final pressure of the tank

Question

Mr Chua experimented on water movement within a rigid tank. The rigid tank is
divided into two equal parts by a partition. Initially, one side of the tank contains 5.0
kg of water at 200 kPa and 25ºC, and the other side is empty. The partition is then
removed, and the water expands into the entire tank. The water is allowed to
exchange heat with its surroundings until the temperature in the tank returns to the
initial value of 25ºC. Determine:
a) the volume of the tank.
b) the final pressure of the tank.
