The Diagram Shows Three Isotherms for an Ideal Gas, with T₃-T₂

The diagram shows three isotherms for an ideal gas, with T₃-T₂ the same as T₂-T₁. It also shows five thermodynamic processes caried out on the gas. Rank the processes in order change in the internal energy of the gas, least to greatest.
