Figure shows two processes a and b for a given sample of gas. If `DeltaQ_1, DeltaQ_2` are the amount of heat absorbed by the systemin the two cases , and `DeltaU_1, DeltaU_2` are changes ininternal energy respeclively, then

A

`DeltaQ_1 = DeltaQ_2, DeltaU_1 = DeltaU_2`

B

`DeltaQ_1 gt DeltaQ_2, DeltaU_1 gt DeltaU_2`

C
