From an initial state where the pressure is \(p_{1}\), the temperature is \(T_{1}\), and the volume is \(V_{1}\), water vapor contained in a piston–cylinder assembly undergoes each of the following processes:

\(\begin{array}{l}\text{Process 1-2: Constant-temperature to } p_{2}=2 p_{1} \text{.}\\\text{Process 1-3: Constant volume to } p_{3}=2 p_{1} \text{.}\\\text{Process 1-4: Constant pressure to } V_{4}=2 V_{1} \text{.}\\\text{Process 1-5: Constant temperature to } V_{5}=2 V_{1} \text{.}\end{array}\)

On a p–V diagram, sketch each process, identify the work by an area on the diagram, and indicate whether the work is done by, or on, the water vapor.
