What happens in a reversible adiabatic expansion process ?
Correct answer: B. Cooling takes place
- A. Heating takes place
- B. Cooling takes place
- C. Pressure is constant
- D. Temperature is constant
Explanation
In a reversible adiabatic process, entropy remains constant, and expansion causes the gas to do work without receiving heat. Its internal energy and temperature consequently decrease, so cooling takes place.
