2 Questions around this concept.
1. Constant Volume Process:
Representation on P-V diagram:
This process is represented on the P-V diagram by a vertical straight line as shown in figure, since V1=V2.
Work done during the process:
Thus, work done during constant volume process is zero which is also evident from the P-V diagram as no area is enclosed by the vertical line on P-V diagram.
2. Constant Pressure Process:
Representation on P-V diagram:
During this process the pressure or the gas remains constant therefore it is represented by a horizontal line on P-V diagram. See figure.
Work done during the process:
The work done by the gas during constant pressure process is represented by a rectangle on P-V diagram.
