Question:

An ideal gas goes through a cycle consisting of
(a) Isochoric, adiabatic, and isothermal lines;
(b) Isobaric, adiabatic, and isothermal lines, with the isothermal process proceeding at V the minimum temperature of the whole cycle. Find the efficiency of each cycle if the absolute temperature varies n-fold within the cycle.
