Question

Entropy change in reversible adiabatic process is:

• A. infinite
• B. zero
• C. equal to $C_V\Delta T$
• D. equal to $nR\ln \left(\frac{V_2}{V_1}\right)$

Answer 1

Answer: (B)

zero

In reversible adiabatic process, there is no heat transfer,

so, the entropy remains constant

and entropy change becomes zero.
