A polyatomic gas ( =4 / 3) is compressed to ( 1 8 )^ th of its volume adiabatically.If its initial pressure is P ₀ , its new pressure will be

Options

  1. A2 P ₀
  2. B8 P ₀
  3. C6 P ₀
  4. D16 P ₀

Correct answer

D. 16 P ₀

Step-by-step solution

For adiabatic expression, we have aligned & P ₂ ~V ₂^ = P ₁ ~V ₁^ & P ₂ P ₁ = ( V ₁ ~V ₂ )^ =(8)^ 4 3 =16 & P ₂=16 P ₁=16 P ₀ aligned
