Thermodynamic process are indicated in the following diagram.

Match the following

Options

A. `P rarr C, Q rarr A, R rarr D, S rarr B`
B. `P rarr C, Q rarr D, R rarr B, S rarr A`
C. `P rarr D, Q rarr B, R rarr A, S rarr C`
D. `P rarr A, Q rarr C, R rarr D, S rarr B`

Answer

A

Explanation

In process I, volume is constant
`:.` Process `I rarr` Isochoric, `P rarr C`
As slope of curve II is more than the slope of curve III. Process `II rarr` Adiabatic and Process `II rarr` Isothermal
`:. Q rarr A, R rarr D`
In process IV, pressure is constant
Process `IV rarr` Isobaric, `S rarr B`
