Question

4. An engine operates on a Carnot cycle that uses 1mole of an ideal gas as the working substance and operates from a most compressed stage of 100 Nm-2 and 327 K. It expands isothermally to a pressure of 90 Nm-2 and then adiabatically to a most expanded stage of 27 K. Calculate the ΔU, q, and w for each step. Calculate the net work done and the efficiency of the cycle [Cv,m for the gas] is 25 J/k/mol.
