And what we can do is, we can actually make a calculation of what the fraction of those phases are as a function of temperature. So above the temperature T6, we have only one phase present. That's 100% liquid. phase involved. (a) The amount of heat transferred is directly proportional to the temperature change. To double the temperature change of a massm, you need to add twice the heat. (b) The amount of heat transferred is also directly proportional to the mass. To cause an equivalent temperature change in a doubled mass, you need to add twice the heat. A phase diagram is a graphical way to summarize the conditions under which equilibria exist between the different states of matter. It also allows us to predict the phase of a substance that is stable at any given temperature and pressure. The general form of a phase diagram for a substance that exhibits three phases is shown in Figure 11.24.
