An ideal gas goes from state A to state B via three different processes as indicated in the P-V diagram -
If `Q_(1),Q_(2),Q_(3)` indicate the heat absorbed by the gas along the three process and `DeltaU_(1),DeltaU_(2),DeltaU_(3)`, indicate 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 U_(1) gt Delta U_(2) gt Delta U_(3)`
D. `Q_(3) gt Q_(2) gt Q_(1)` and `Delta U_(1) gt Delta U_(2) Delta U_(3)`

Answer

A
