In the figure given two processes A and ...

In the figure given two processes `A and B` are shown by which a thermodynamic system goes from initial to final state F. if `DeltaQ_(A)` and `DeltaQ_(B)` are respectively the heats supplied to the systems then

A

`DeltaQ_1 gt DeltaQ_2`

B

`DeltaQ_1=DeltaQ_2`

C

`DeltaQ_1 lt DeltaQ_2`

D

`DeltaQ_1leDeltaQ_2`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaU_A=DeltaU_B,DeltaW_AgtDeltaW_B` (since area below the process `Agt` area below the process B)
`DeltaQ_1=DeltaU_A+DeltaW_A,DeltaQ_2=DeltaU_B+DeltaW_B)`
`DeltaQ_1gtDeltaQ_2`
