The initial state of 1 mol of an ideal gas is `(P_(1),V_(1),T_(1))`. The gas is expanded by a reversible isothermal process and also by a reversible adiabatic process separately. If final volume of the gas is same in both the processes, and changes in internal energy in the isothermal and adiabatic processes are `DeltaU_(1)` and `DeltaU_(2)` respectively, then-

A

`DeltaU_(1)=DeltaU_(2)`

B

`DeltaU_(1) lt DeltaU_(2)`

C

`DeltaU_(1) gt DeltaU_(2)`

D

cannot be predicted
