The pressure and density of a given mass of a diatomic gas ( = 7 5 ) change adiabatically from (P, d) to (P^ , d^ ) . If d^ d =32 , then P^ P is ( = ratio of specific heats )

Options

  1. A1 128
  2. B1 64
  3. C64
  4. D128

Correct answer

D. 128

Step-by-step solution

aligned & p V^ = p ^ = constant & p^ p = ( ^ )=(32)^ 7 / 5 & =32 4=128 & aligned
