MCQ
Three samples of the same gas $A, B$ and $C \left(\gamma=\frac{3}{2}\right)$ 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 the three samples, the ratio of their initial pressures is:
- A$\sqrt{2}: 1: 2$
- B$2: 1: \sqrt{2}$
- C$2 \sqrt{2}: 2: 1$
- D$2 \sqrt{2}: 1: 2$
