Consider one mole of an ideal gas in a closed system. It undergoes a change in state from L to N through two different non- isothermal processes, as shown in the P-V diagram (where P is the pressure and V is the molar volume of the gas). Process I is carried out in a single step, namely LN, whereas process II is carried out in two steps, namely LM and MN. All the steps are reversible.
The net heat flowing into the system for process I is QI and that for process II is QII. The value of Q I – Q I I (in J) is
