Match List I with List II.
$$\begin{array}{|l|l|l|l|}\hline & \text{List I} & & \text{List II} \\ \hline \text{A.} & \text{Isothermal process} & \text{I.} & \text{Work done by the gas decreases internal energy} \\ \hline \text{B.} & \text{Adiabatic process} & \text{II.} & \text{No change in internal energy} \\ \hline \text{C.} & \text{Isochoric process} & \text{III.} & \text{The heat absorbed goes partly to increase internal energy and partly to do work} \\ \hline \text{D.} & \text{Isobaric process} & \text{IV.} & \text{No work is done on or by the gas} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (B) A-II, B-I, C-IV, D-III
- Isothermal: $\Delta U=0$ → II
- Adiabatic: $Q=0$, so $W=-\Delta U$ → I
- Isochoric: $\Delta V=0$, no work → IV
- Isobaric: $Q=\Delta U+P\Delta V$ → III
