Explanation:

A Carnot cycle consists of four processes:

  1. Reversible isothermal heat addition
  2. Isentropic (reversible adiabatic) expansion
  3. Reversible isothermal heat rejection
  4. Isentropic compression of the gas

\({\eta_{Carnot}} = \frac{{{T_3} - {T_1}}}{{{T_3}}}\)

Stirling cycle and Ericsson cycle are the modified forms of Carnot cycle.

A stirling cycle consists of two reversible isothermal and two reversible constant volume (isochoric) processes.
