A closed container with constant volume insulated against heat is divided into two compartments by a steel curtain. Compartment A contains 2 kg of water at 800 kPa pressure and 80 oC temperature. The other compartment is empty (vacuum). Then the steel curtain is removed and the water fills the whole container. Finally, calculate the final temperature of the water and the volume of the tank, since the pressure of the water in equilibrium is 10 kPa.
