p-V diagram:
- It is a curve which shows the variation of pressure and volume of a substance.
- It is also called an indicator diagram.
- The shape of the P-V curve depends upon the nature of the thermodynamic process.
- With the help of a -V diagram one can able to calculate the value of pressure and volume at various instants.
The above-given curve is a thermodynamic cycle as the system attains its initial state after undergoing a series of processes.
The processes in the above thermodynamic cycle are:
- Process 1-2: Compression process (isentropic compression)
- Process 2-3: Constant pressure heat rejection process (condensation process)
- Process 3-4: Throttling process (in this process enthalpy is remain the same)
- Process 4-1: Constant pressure heat addition process (evaporation process).
Thus, option (4) is the correct answer.
