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 $94\mathrm{.}0$ kPa and the volume is $4\mathrm{.}00$ 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 $94\mathrm{.}0$ kPa ;

process $C$ is an isothermal process that returns the system to a volume of $4\mathrm{.}00$ 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.
