For all adiabatic processes:
Correct answer: D. The entropy of the system does not decrease
- A. The entropy of the system does not change
- B. The entropy of the system increases
- C. The entropy of the system decreases
- D. The entropy of the system does not decrease
Explanation
Essential conditions for the adiabatic process to take place are: i) System is perfectly insulated from surrounding. ii) The process must be carried out rapidly so that the system has sufficient time to exchange heat with the surroundings. Adiabatic processes are characterized by an increase in entropy, or degree of disorder, if they are irreversible and by no change in entropy if they are reversible. Adiabatic processes cannot decrease entropy.
