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 processes and Delta U_(1) , Delta U_(2), Delta U_(3) indicate the change in internal energy along the three processes respectively, then

Answer»

`Q_(1) GT Q_(2) gt Q_(3)` and `Delta U_(1) = Delta U_(2) = Delta U_(3)`
`Q_(1) gt Q_(2) gt Q_(3)` and `Delta U_(1) = Delta U_(2) = Delta U_(3)`
`Q_(1) = Q_(2) = Q_(3)` and `Delta U_(1) gt Delta U_(2) gt Delta U_(3)`
`Q_(3) gt Q_(2) gt Q_(1)` and `Delta U_(1) gt Delta U_(2) gt Delta U_(3)`
