Passage / Comprehension
A cylindrical container of volume 89.6 L is containing equal number of moles of an ideal monoatomic gas in two sections A and B, separated by an adiabatic frictionless piston as shown in the figure. The initial temperature and pressure of gas in both sections is 54.6 K and 2 atm. Now, gas in section A is slowly heated till the volume of section B becomes one-eighth of its initial volume.
What will be the final pressure of gas in Section B?
Options:
Answer:
D
Solution:
Initially each section holds 44.8 L; finally VB = 44.8/8 = 5.6 L. B is compressed quasi-statically and adiabatically (γ = 5/3): PB = P₀(V₀/VB)γ = 2 × 8^(5/3) = 2 × 32 = 64 atm. Matches (d).
