Figure shows two processes a and b for a given sample of a gas. If `DeltaQ_1`, `DeltaQ_2` are the amounts of heat absorbed by the system in the two cases and `DeltaU_1`, `DeltaU_2` are changes in internal energies respectively, then

Text Solution

Verified by Experts

The correct Answer is:
A, B
`Q_1=W_1+DeltaU_1` and `Q_2=W_2+DeltaU_2`

U is a state function. Hence, `DeltaU` depends only on the initial and final position. Therefore,
`DeltaU_1=DeltaU_2`
But, `W_1 gt W_2`
as the area under 1 is greater than area under 2. Hence,
