One mole of an ideal gas goes from an initial state A to final state B via two processes. It first undergoes isothermal expansion from volume V to 3 V and then its volume is reduced from 3 V to V at constant pressure. The correct p-V diagram representing the two processes is

Correct answer

3

Step-by-step solution
