Carnot cycle consists of
Correct answer: C. Both adiabatic and isothermal steps
- A. Isothermal steps only
- B. Adiabatic steps only
- C. Both adiabatic and isothermal steps
- D. Neither adiabatic nor isothermal
Explanation
The Carnot cycle consists of two isothermal and two adiabatic processes.These steps are essential for its maximum efficiency.Therefore, this is the correct answer.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
