Carnot cycle is one of the best-known reversible cycles. The Carnot cycle is composed of four reversible processes.
- Reversible Isothermal Expansion (process 1-2)
- Reversible adiabatic expansion (process 2-3)
- Reversible isothermal compression (process 3-4)
- Reversible adiabatic compression (process 4-1)

The correct answer is option 'B': Two reversible isothermal and two reversible adiabatic processes.
Explanation:
Carnot cycle is a theoretical thermodynamic cycle that consists of four processes: two isothermal processes and two adiabatic processes. Let's understand each process in detail:
1. Isothermal Process:
- In an isothermal process, the temperature of the system remains constant.
- During this process, heat is added or removed from the system to maintain the constant temperature.
- The heat transfer occurs at a constant temperature, resulting in a change in the system's internal energy.
- In the Carnot cycle, two isothermal processes are involved, one at a higher temperature (T1) and the other at a lower temperature (T2).
2. Adiabatic Process:
- An adiabatic process is a process in which there is no heat transfer between the system and its surroundings.
- In this process, the system's internal energy changes due to work done on or by the system.
- The temperature of the system can change during an adiabatic process.
- In the Carnot cycle, two adiabatic processes are involved, one where the gas expands (cooling) and the other where the gas is compressed (heating).
So, in the Carnot cycle, the four processes are as follows:
- Process 1: Isothermal expansion (heat added at T1)
- Process 2: Adiabatic expansion (no heat transfer)
- Process 3: Isothermal compression (heat removed at T2)
- Process 4: Adiabatic compression (no heat transfer)
Hence, the correct answer is option 'B': Two reversible isothermal and two reversible adiabatic processes.
