Problem 1: Propane is isothermally compressed from 0.01 bar, -51.4 °C to 17 bar. The process takes place reversibly in a closed system. a) Draw the PV graph of the process. b) Calculate the entropy change of propane. c) How much heat is exchanged between the system and its surroundings? Is this heat added to or removed from the system? Additional data: Use the Lee-Kesler graphs for enthalpy and entropy. The saturation pressure of propane at -51.4 °C is 0.66 bar. Take the ideal-gas CP of propane at these conditions to be constant and equal to 67 J/mole K.
