In a Carnot cycle, the isothermal expansion occurs at:
Correct answer: C. Constant temperature
- A. Constant pressure
- B. Constant volume
- C. Constant temperature
- D. Constant entropy
Explanation
In Carnot cycle, the isothermal expansion occurs at constant temperature, where the gas absorbs heat from a reservoir and expands while maintaining the same temperature.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
