Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process.
Reason (R): In an isothermal process, , while in an adiabatic process . Here, is the ratio of specific heats, is the pressure and is the volume of the ideal gas.
In the light of the above statements, choose the correct answer from the options given below:
- A
Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
- B
(A) is true but (R) is false
- C
Both (A) and (R) are true and (R) is the correct explanation of (A)
- D
(A) is false but (R) is true
