A system undergoes a reversible adiabatic process. The entropy of the system

Options

  1. ARemains constant
  2. BMay increase or may decrease
  3. CIncreases
  4. DDecreases

Correct answer

A. Remains constant

Step-by-step solution

In general, the temperature of the system may change during a process. If the process is reversible, the change in entropy is defined as S f - S i = ∫ i f ∆ Q T In an adiabatic reversible process, no heat is given to the system. Therefore, entropy of the system remains constant.
