A Carnot cycle consists of the following steps ?
Correct answer: D. Two isothermal and two isentropic
- A. Two isothermals and two isochoric
- B. Two isobaric and two isothermal
- C. Two isochoric and two isobaric
- D. Two isothermal and two isentropic
Explanation
A reversible Carnot cycle has two constant-temperature heat-transfer processes and two reversible adiabatic processes. Reversible adiabatic processes are isentropic, giving two isothermal and two isentropic steps.
