Thermodynamics

Step 1: Understand each process and corresponding work done.
Let’s review the work done for each thermodynamic process: Isothermal process (A): In this process, the temperature remains constant. The work done is given by: Hence, the correct matching for A is III. Adiabatic process (B): In this process, there is no heat exchange, and the work done is related to the change in temperature by the formula: Hence, the correct matching for B is IV. Isochoric process (C): In this process, the volume is constant, so no work is done. Therefore, the work done is zero. Hence, the correct matching for C is I. Isobaric process (D): In this process, the pressure is constant, and the work done is given by: Hence, the correct matching for D is II.
Step 2: Conclusion.
The correct answer is (1) A-III, B-IV, C-I, D-II.
