Sketch the following processes on P-V and P-T diagrams
a. Superheated vapor is cooled at constant pressure until liquid just begins to form.
b. A liquid-vapor mixture with a quality of 60% is heated at constant volume until its quality is 100%
c. A liquid-vapor mixture of water with a quality of 50% is heated at a constant temperature of 200C until its volume is 4.67 times the initial volume.
