A monoatomic gas is suddenly compressed to (1 / 8)^ th of its initial volume adiabatically. The ratio of the final pressure to initial pressure of the gas is ( =5 / 3)

Options

  1. A32
  2. B8
  3. C40 3
  4. D24 5

Correct answer

A. 32

Step-by-step solution

V ₂ ~V ₁ = 1 8 , = 5 3 For adiabatic process, P ₁ ~V ₁^ = P ₂ ~V ₂^ P ₂ P ₁ = ( V ₁ ~V ₂ )^ =(8)^ 5 / 3 =(2)^5=32
