Question

6.7 mol of a diatomic, ideal gas at 21.2°C and 109.67 kPa is sealed inside a piston. The piston is then cycled through a Carnot process beginning with an isothermal compression that reduces the volume of the gas inside the piston to half. The efficiency of the process is 35% and it runs at 5.57 Hz. (a) Draw a PV diagram for this process and label each point in the cycle with its corresponding pressure, volume, and temperature. (b) What is the total amount of work done by this process during one cycle? (c) How much heat flows into the system in one cycle? (d) How much heat flows out of the system in one cycle? (e) How much power is generated/consumed?
