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)?

When dealing with specific heat of an ideal gas. For the example of finding Cp=a+bT+cT^2+dT^3 what is the relation of the coefficients to the universal gas constant Ru? For example when finding Cv instead Cv=(a-Ru)+bT+cT^2..... why is only 'a' affected by Ru?

Consider a reversible adiabetic compression of an ideal gas with CV,m = 3R/2 and CP,m = 5R/2. 3.0 mol of this ideal gas with a volume of 30.0 L changes from an initial temperature of 300 K to a final temperature of 600 K. For this process, compute the final volume.

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?
