Consider the following four-process cycle that is carried out on a system of monatomic ideal gas, starting from state 1 in which the pressure is 84.0 kPa and the volume is 4.00 liters.
Process A is an isothermal process that triples the volume;
process B is a constant volume process that returns the system to a pressure of 84.0 kPa;
process C is an isothermal process that returns the system to a volume of 4.00 liters;
and process D is a constant volume process that returns the system to state 1.
You should sketch a P-V diagram for this cycle, to help you understand it.
Complete the table below. For each process, and the entire cycle, find the heat added to the gas, the work done by the gas, and the change in internal energy.
