60 mol/s of liquid cyclohexane undergoes a heating process. The liquid starts at 30 bar and 150C and ends as a vapor at 4 bar and 550C. Assume the liquid heat capacity data in Appendix Table C.3 is invalid at this pressure range. However, it is known that the volume expansivity takes the value = 1.1 104 1 , and the liquid molar volume is approximately constant and equal to the saturated liquid volume at 150C. Calculate the total enthalpy change for this process.
