2. 1 kg of an ideal gas within a piston-cylinder assembly executes a Carnot cycle as shown in
the T-s diagram shown below. The pressure at the start of the isothermal expansion is 4
bar. The gas has a molar mass of 20 g/mol. Determine:
a. if the process a power cycle or a heat pump/refrigeration cycle
b. the magnitude of the net work input/output, in kJ.
c. the heat transfer that occurs during the isothermal compression, in kJ, and
d. the pressure at the end of the isothermal expansion, in kPa.
