Problem 2 (20 points) A rigid tank is divided into two rooms, both containing water, by a membrane. Room A is at TA1=110C,vA1= 0.5m3/kg and VA1=1m3, and room B contains mB1= 3.5kg at TB1=300C and PB1=0.4MPa. The membrane now ruptures, and heat transfer takes place so that the water comes to a uniform state at T2=100C. Please determine the phases of rooms A and B at the initial state and the phase at the final state. Problem 2 (20 points) A rigid tank is divided into two rooms, both containing water, by a membrane.
