Figure 3.1 Constant-pressure change from liquid to vapor phase for a pure substance. Note: Heat is added below the cylinders.

• Can you sketch a piston/cylinder set-up for a constant-temperature process from liquid to vapor phase for the water, as compared to the above Fig. 3.1?

• Can you draw this constant-temperature process on a P – v diagram?

• A piston/cylinder set-up for a constant-temperature process for an ideal gad is given in comments and Figure 4.7 of Example 4.1.b (pay attention to the change in pressure as heat is transferred in the process)
