Question

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 :

Options:

Answer:

B

Solution:

If the container is insulated then temperature is expected to increase in adiabatic compression. So (A) is wrong.
And free expansion is irreversible and adiabatic process. So (R) is correct.
