Cp is always greater than Cv because heat added at constant pressure will change internal energy and do work but at constant volume work done is zero and added heat will only increase internal energy.
No, Cp is less than Cv is not valid for liquids, it is always greater than or equal to Cv.

A. Compute Cp-Cv for a gas described by the equation of state p= RT/V-b B. For this equation of state, does a measurement of Cp-Cv reveal non-ideal behavior (give ≈ 1 sen- tence justification why or why not)?

2. One mole of an ideal gas, CP - (7/2)R and CV - (5/2)R, is compressed adiabatically in a piston/cylinder device from 2 bar and 25°C to 7 bar. The process is irreversible and requires 35% more work than a reversible, adiabatic compression from the same initial state to the same final pressure. What is the entropy change of the gas?

1 - Solve the items of applied chemical thermodynamics Determine a relationship between Cp and the PVT properties of any substance. Tip: Start from the definition of Cp and fundamental relationships. If the previous substance behaves as the ideal gas, show that Cp and Cv are independent of the pressure. What is the relationship between Cp and pressure for a compressed liquid if the isobaric expansion coefficient is independent of pressure. If a gas can be described by the Clausius...
