(a) Use the Clausius–Clapeyron equation and data for water at 100°C to develop an expression for the vapor pressure of water as a function of temperature.

(b) Plot the expression you came up with on a PT diagram for temperatures from 0.01°C to 100°C.

(c) Include data from the steam tables on your plot in part

(b) and comment on the adequacy of the Clausius–Clapeyron equation.

(d) Repeat parts (b) and (c) for 100°C to 200°C.

(e) Repeat parts (a)–(c), but correct for the temperature dependence of Dhvap, using heat capacity data from Appendix A.2.
