Thermodynamics Test 2

An ideal gas goes from state A to state B via three different processes as indicated in the P-V diagrams:

If Q₁, Q₂, Q₃indicates the heat absorbed by the gas along the three processes and ΔU₁, ΔU₂, ΔU₃indicates the changes in internal energy along the three processes respectively, then
