Assertion : Work done during free expans...

Assertion : Work done during free expansion of an ideal gas whether reversible or irreversible is positive.
Reason : During free expansion, external pressure is always less than the pressure of the system.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
During the free expansion, in vaccum `P_("ex")=0` ltbr? Hence, no work is done whether the process is reversible or irreversible.
