Question:
The Carnot's Cycle consists of
The Carnot's Cycle consists of
Show Hint
Think of it as a symmetric four-step loop: Expand (Iso-Adi) then Contract (Iso-Adi).
Updated On: Jul 4, 2026
- One isothermal and one adiabatic step
- Two isothermal and two adiabatic steps
- One isothermal and three adiabatic steps
- Three isothermal and one adiabatic step
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
The Carnot cycle is a theoretical thermodynamic cycle that provides an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conversion of heat into work.
Step 2: Meaning
It is a reversible cycle consisting of four distinct processes that return the working substance to its original state.
Step 3: Analysis
The sequence involves: 1. Reversible isothermal expansion, 2. Reversible adiabatic expansion, 3. Reversible isothermal compression, and 4. Reversible adiabatic compression.
Step 4: Conclusion
This sequence confirms the presence of exactly two isothermal processes and two adiabatic processes. Final Answer: (B)
