An ideal gas goes from State A to state B via three different process as indicate in the `P-V` diagram.

If `Q_(2), Q_(3)` indicates the heat absorbed by the gas along the three processes and `DeltaU_(1), DeltaU_(2), DeltaU_(3)` indicates the change in internal energy along the three processes respectively, then

Options

A. `Q_(1) gt Q_(2) gt Q_(3)` and `Delta U_(1) = Delta U_(2) = Delta U_(3)`
B. `Q_(3) gt Q_(2) gt Q_(1)` and `Delta U_(1) = Delta U_(2) = Delta U_(3)`
C. `Q_(1) = Q_(2) = Q_(3)` and `Delta I_(1) gt Delta U_(2) gt Delta U_(3)`
D. `Q_(3) gt Q_(3) gt Q_(1)` and `Delta U_(1) gt Delta U_(2) gt Delta U_(3)`

Answer

A
