5 Pool Boiling
From the viewpoint of thermodynamics, when a body of fluid in the purely liquid phase is heated at a constant pressure, its temperature and volume will both increase, as reflected in the line from A to B in Figure 5.1. Point B represents the maximum temperature and volume of saturated liquid at the given pressure, and between points B and C, any additional heat added to the system results in a change from the liquid phase to the vapor phase. In this region, liquid and vapor phases coexist in equilibrium. The amount of heat required to convert a unit...
