In ________________ process, there is an increase in entropy with no degradation of energy ?
Correct answer: A. Isothermal expansion
- A. Isothermal expansion
- B. Isochoric heat addition
- C. Polytropic expansion
- D. Isobaric heat addition
Explanation
During reversible isothermal expansion of an ideal gas, entropy increases as the gas expands, while its temperature and internal energy remain constant. This distinguishes it from heat-addition processes, where energy is added to the system.
