Match List - I with List - II.
Given $\displaystyle \mathrm{V}_1$ and $\displaystyle \mathrm{V}_2$ are initial and final volumes respectively.
Choose the correct answer from the options given below :
| List - I (Isothermal process) | List - II (Expression) | ||
| A. | Reversible expansion | I. | $\displaystyle \mathrm{q}=0$ |
| B. | Free expansion | II. | $\displaystyle \mathrm{q}=\mathrm{nRT} \ln \frac{\mathrm{V}_2}{\mathrm{~V}_1}$ |
| C. | Irreversible Compression | III. | $\displaystyle \mathrm{w}=-\mathrm{p}_{\text {ext }}\left(\mathrm{V}_1-\mathrm{V}_2\right)$ |
| D. | Cyclic reversible | IV. | $\displaystyle \frac{\mathrm{q}_{\text {rev }}}{\mathrm{T}}=0$ |
