MCQ
Three samples of the same gas $A, B$ and $C(\gamma = 3/2)$ have initially equal volume. Now the volume of each sample is doubled. The process is adiabatic for $A$ isobaric for $B $ and isothermal for $C$. If the final pressures are equal for all three samples, the ratio of their initial pressures are
- A$2\sqrt 2 \,\,:\,\,2\,\,:\,\,1$
- ✓$2\sqrt 2 \,\,:\,\,1\,\,:\,\,2$
- C$\sqrt 2 \,\,:\,\,1\,\,:\,\,2$
- D$2\,\,:\,\,1\,\,:\,\,\sqrt 2 $
