A diatomic gas undergoes adiabatic change. Its pressure 'P' and temperature 'T' are related as P T ^ x , where x is

Options

  1. A3.0
  2. B2.5
  3. C3.5
  4. D1.5

Correct answer

C. 3.5

Step-by-step solution

(D) array ll Adiabatic change PV ^ = k & PV = RT P R ^ T ^ p ^ = k & V ^ = ( RT P )^ array P ^ 1- T ^ = k ^ P ^ 1- = k ^ T ^ P= k^ n T^ / 1- =k^ n T ( 1- ) x = -1 For diatomic gas =1.4 x= 1.4 0.4 =3.5
