Problem 5.8:

a) What is the residual volume of saturated liquid water at 1 bar?

b) Estimate the residual volume of ethanol vapor at 1 bar and 100 °C.

c) Use the generalized graphs to calculate the entropy change of 1 mole of ethanol undergoing isothermal compression from 1 bar to 100 bar along the critical isotherm.

Problem 5.9: n-Octane is compressed reversibly at constant temperature along the critical isotherm until the critical point is reached. The initial pressure is 1 bar. The pressure takes place in a closed system. Use the Lee-Kesler method to calculate the following:

a) What is the entropy change of n-octane?

b) Calculate the heat that must be supplied to the system to maintain isothermal conditions.

c) Calculate the necessary amount of work.
