JEE Main 2025 — 29 January, Evening Shift — Question 18
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 isothermal process, PV = constant, while in adiabatic process constant. Here is the ratio of specific heats, P is the pressure and V is the volume of the ideal gas.
In the light of the above statements, choose the correct answer from the options given below
- Option A:
Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
- Option B:
(A) is true but ( ) is false
- Option C:
Both (A) and (R) are true and (R) is the correct explanation of (A).
- Option D:Correct
(A) is false but (R) is true
Answer: D
