Figure \(P 20. 28\) is the \(P V\) diagram for a process carried out on \(10 \mathrm{~mol}\) of an ideal gas in thermal equilibrium that begins and ends on the same state (the initial state \(i\) and the final state \(\mathrm{f}\) for the gas are at 1).

(a) Characterize each leg of the process \(-1 \rightarrow 2,2 \rightarrow 3,3 \rightarrow 4,4 \rightarrow 1-\) as being isothermal, isobaric, isochoric, or isentropic.

(b) Determine the temperature at state 1 and at state 3.
