Carnot Cycle
1 / 10
The Carnot cycle assumes:
Explanation: Reversible, frictionless processes maximize efficiency, unlike irreversible or real gas cycles. Heat transfer varies, not remains constant.
2 / 10
In the Carnot cycle’s adiabatic expansion:
 Explanation: Adiabatic expansion lowers temperature via work, unlike isothermal processes or heat absorption in expansion. Internal energy changes, not stays constant.
3 / 10
The Carnot cycle is typically modeled in:
Explanation: Piston-cylinders allow volume changes for isothermal and adiabatic processes, unlike rigid containers or pipes in other systems. Heat exchangers involve heat transfer.
4 / 10
During the Carnot cycle’s isothermal compression:
Explanation: Isothermal compression rejects heat to the cold reservoir, unlike absorption in expansion or temperature changes in adiabatic processes. Work is non-zero.
5 / 10
The Carnot cycle is significant because it:
Explanation: The Carnot cycle defines the maximum efficiency for heat engines, unlike real gas cycles or constant-volume processes. Work is produced, not zero.
6 / 10
The efficiency of a Carnot cycle is determined by:
 Explanation: Efficiency relies on hot and cold reservoir temperatures (η = 1 - Tc/Th), unlike work or volume in other cycles or pressure ratios in real engines.
7 / 10
The adiabatic processes in the Carnot cycle involve:
Explanation: Adiabatic processes have no heat transfer, unlike isobaric or isothermal processes with heat exchange. Volume and temperature change, not remain
8 / 10
In the Carnot cycle’s isothermal expansion, the system:
Explanation: Isothermal expansion absorbs heat at constant temperature, unlike rejection in compression or no heat in adiabatic processes. Work is done, not zero.
9 / 10
The Carnot cycle operates between:
Explanation: Heat transfer occurs between hot and cold temperature reservoirs, unlike pressure or volume-based systems in other cycles. Entropy reservoirs are not relevant.
10 / 10
The Carnot cycle consists of how many processes?
Explanation: The Carnot cycle includes two isothermal and two adiabatic processes, unlike cycles with fewer or more steps. Four processes define its reversible structure.
