Hello, I need help with the following problem!

An air-standard Otto cycle is often used as a very simplified model of a spark-
ignition engine. The following sequence of processes applied to a fixed mass of
air in a piston-cylinder assembly constitutes the Otto cycle:
1-2: Internally reversible, adiabatic compression from the maximum volume
Vmax to the minimum volume Vmin:
bnsists
2-3:
Constant-volume heat addition to a peak cycle temperature T3.
3–4: Internally reversible, adiabatic expansion from Vmin to Vmax-
4-1:
Constant-volume heat rejection to return to the initial state.
Sketch this cycle using P-V and T-S coordinates, labeling each state point
the
(1, 2, 3, and 4).
ecycle, Compute the no
