Vedclass · Answer

(B) Carnot engine is a theoretical model of a heat engine proposed by Sadi Carnot in $1824$. It operates on a reversible cycle known as the Carnot cycle,which consists of two isothermal processes and two adiabatic processes. It provides the theoretical upper limit for the efficiency of any heat engine operating between two given temperatures,$T_H$ (hot reservoir) and $T_L$ (cold reservoir). The efficiency of a Carnot engine is given by $\eta = 1 - \frac{T_L}{T_H}$,where temperatures are in Kelvin. Since it is a reversible cycle,it is the most efficient engine possible between two heat reservoirs.
