A 25-L sample of an ideal gas with ? = 1.67 is at 250 K and 50kPa. The gas is compressed adiabatically until its pressuretriples, then cooled at constant volume back to 250 K, and finallyallowed to expand isothermally to its original state.
a. Sketch this cyclical process in a pV diagram (the sketchshould be drawn to scale and labelled).
b. How much work is done on the gas?
c. For each step in the process determine the heat energy.
