One mole of a monatomic ideal gas undergoes four thermodynamic processes as shown schematically in the $$PV$$-diagram below. Among these four processes, one is isobaric, one is isochoric, one is isothermal and one is adiabatic. Match the processes mentioned in List-I with the corresponding statements in List-II.

LIST - I | LIST - II | ||
---|---|---|---|
P. | In process I | 1. | Work done by the gas is zero |
Q. | In process II | 2. | Temperature of the gas remains unchanged |
R. | In process III | 3. | No heat is exchanged between the gas and its surroundings |
S. | In process IV | 4. | Work done by the gas is 6P0V0 |

An ideal gas is undergoing a cyclic thermodynamic process in different ways as shown in the corresponding $$P-V$$ diagram in column 3 of the table. Consider only the path from state $$1$$ to state $$2.$$ $$W$$ denotes the corresponding work done on the system. The equations and plots in the table have standard notations as used in thermodynamic processes. Here $$Y$$ is the ratio of heat capacities at constant pressure and constant volume. The number of moles in the gas is $$n.$$


Which one of the following options is the correct combination?
