A reversible compression of 1 mol of an ideal gas in a piston/cylinder device results in a pressure increase from 1 bar to P2 and a temperature increase from 500 K to 1000 K. The path followed by the gas during compression is given by:

PV1.55 = constant

and the molar heat capacity of the gas is given by:

CP/R = 3.30 + 0.63x10-3 T (T in K)

Determine the final pressure and the heat transferred during the process.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?
