Reversible expansion of an ideal gas under isothermal and adiabatic conditions are as shown in the figure. Which of the following options is INCORRECT?

  1. \( T_C > T_A \)
  2. \( \Delta S_{\text{isothermal}} > \Delta S_{\text{adiabatic}} \)
  3. \( T_A = T_B \)
  4. \( W_{\text{isothermal}} > W_{\text{adiabatic}} \)

Correct answer · Option 1

\( T_C > T_A \)

Explanation

In adiabatic expansion, temperature falls, so \( T_C < T_A \), making option A incorrect.
