Question:

A rigid tank with a volume of 3.5 m3 contains 5 kg of saturated liquid-vapor mixture of H2O at 80oC. The tank is slowly heated until all the liquid in the tank is completely vaporized. Determine the temperature at which this process occurred. Also show the process on a T-v diagram with respect to saturation lines.
