Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): In an insulated container, a gas is adiabatically shrunk to half of its initial volume. The temperature of the gas decreases.
Reason (R): Free expansion of an ideal gas is an irreversible and an adiabatic process.
In the light of the above statements, choose the correct answer from the options given below:
- A
(A) is true but (R) is false
- B
Both (A) and (R) are true and (R) is the correct explanation of (A)
- C
Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
- D
(A) is false but (R) is true
