102) 2.37 moles of an ideal monatomic gas initially at 255 K undergoes this cycle: It is (1) heated at constant pressure to 655 K, (2) then allowed to cool at constant volume until its temperature returns to its initial value, (3) then compressed isothermally to its initial state. Find:

a. the net energy transferred as heat to the gas (excluding the energy transferred as heat out of the gas).

b. the net work done by the gas for the cycle.

c. the efficiency of this cycle.

d. What would be the efficiency of a Carnot Engine operating between the two heat reservoirs at 275 K and 645 K.

    A Carnot cycle is conducted using an ideal diatomic gas. Initially, the gas is at temperature 25C., pressure of 100KPa and volume of 0.01m3. The system is then compressed isothermally to a volume 0.002m3. From that point, the gas undergoes an adiabatic compression ( with gamma= 1.4), until the volume further reduces to 0.001m3. After that, the system goes an isothermal expansion process to a point where the pressure of the system is 263.8KPa. Then the system continues the cycle...
