Statement-1: In isothermal process whole of the heat energy suppled to the body is converted into internal energy
Statement-2: According to the first law of themodynamics.
`DeltaQ=DeltaU+PDeltaV`

A

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

B

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

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D

As there is no change in internal energy of the system during an FLOT `DeltaQ=DeltaU + PDeltaV`
Hence `DeltaQ=DeltaU + PDeltaV, DeltaU=0" ":. DeltaQ = PDeltaV`
Therefore, reason is true and assertion is false.
