Three separate reversible processes $\left(1,2 \mathrm{and} 3\right)$ are carried out with $1$ mole of an ideal gas initially at STP. In these processes, the pressure ($\mathrm{P}$) is measured while increasing any one of the quantities volume ($\mathrm{V}$), temperature ($\mathrm{T}$) and number of moles $\left(\mathrm{n}\right)$, keeping the other two constant. Plots of $\mathrm{P}\left(\mathrm{atm}\right)$ versus $\mathrm{X}$ are found to be linear, where $\mathrm{X}=\mathrm{n}$ or $\mathrm{T}\left(\mathrm{K}\right)$ or $1/\mathrm{V} \left({\mathrm{lit}}^{-1}\right)$. For the processes $1,2$ and $3$, the numerical values of the slopes ${\mathrm{m}}_1,{\mathrm{m}}_2$ and ${\mathrm{m}}_3$ of the $\mathrm{P}$ versus $\mathrm{X}$ plots are found to follow the order ${\mathrm{m}}_1>{\mathrm{m}}_2>{\mathrm{m}}_3$, respectively. The correct statement(s) about these processes is/are

Consider a cyclic process $\mathrm{P}\to \mathrm{Q}\to \mathrm{R}\to \mathrm{P}$ for a system. Among the following, the combination of steps that can never lead to this cyclic process is

In thermodynamics, a process is called reversible when.

Out of molar entropy $\left(\mathrm{I}\right),$ specific volume $\left(\mathrm{II}\right),$ heat capacity $\left(\mathrm{III}\right),$ volume $\left(\mathrm{IV}\right),$ extensive properties are
