Question

Five moles of a gas is put through a series of changes as shown graphically in a cyclic process. The processes $A\to B$, $B\to C$ and $C\to A$ respectively are ?

• A. isochoric, isobaric, isothermal
• B. isobaric, isochoric, isothermal
• C. isothermal, isobaric, isochoric
• D. isochoric, isothermal, isobaric.

Answer 1

The correct option is A isochoric, isobaric, isothermal

A$\to$B is an isochoric process, as the line is parallel to temperature axis and constant for volume axis.

B$\to$C is an isobaric process, as the line is inclined to temperature axis and the ratio or slope (m) is equal to $\frac{V}{T}$ is constant.

C$\to$A is an isothermal process, as the line is parallel to volume axis and constant for temperature axis.
