The ratio of the specific heats C _ p C _ v = in terms of degrees of freedom 'n' is given by

Options

  1. A(1+ n 2 )
  2. B(1+ 1 n )
  3. C(1+ 10 3 )
  4. D(1+ 2 n )

Correct answer

D. (1+ 2 n )

Step-by-step solution

C_ v =n R 2 ;C_ p =C_ v +R= n R 2 +R= ( n 2 +1 ) R C_ p C_ v = ( n 2 +1 ) R n R 2 = (1+ 2 n ) R
