The following data are available for liquid ethanol at 20 C:

M.W. = 46.07, Density = 0.7893 g/cc, Coefficient of thermal expansion = 1.12x10^-3 K^-1, Isothermal compressibility = 1.0x10^-4 bar^-1

(a) Estimate the difference (Cp-Cv) for liquid ethanol at 20 C in J/mol K

(b) 10 liters of liquid ethanol at 20 C is compressed isothermally from initial pressure of 1 bar to a final pressure of 50 bar. For this process, calculate the enthalpy and entropy change of the liquid.
