A rigid, well-insulated tank contains a two-phase mixtureconsisting of 0.005 ft3 of saturated liquid water and 2.7 ft3 ofsaturated water vapor, initially at 14.7 lbf/in.2 A paddle wheelstirs the mixture until only saturated vapor remains in the tank.Kinetic and potential energy effects are negligible. For the water,determine the amount of energy transfer by work, in Btu.
