A vessel of 2 m3-capacity is filled with 0.02 m3 of liquid water and 1.98 m3 of water vapor at 101.33 kPa. How much heat must be added to the contents of the vessel so that the liquid water is just evaporated?

A rigid tank (0.010 m³) contains saturated liquid water at 160 deg C. How much heat (kJ) must be added for the pressure to be 800 kPa and a temperature of 200 deg C?

Calculate the workin Btu? Is this work useful or spent on the system? What is the magnitudeof change in internal energy of the system at this part of the process?(d)Show the process in a p-V diagram

A 2.8 m^3 rigid tank is filled with saturated liquid vapor mixture of water at 300C. If 2% of its volume is liquid and the rest is vapor, the total mass in the tank in kg is?
