A diatomic gas ( =1.4) does 100 ~J of work in an isobaric expansion. The heat given to the gas is :

Options

  1. A250 ~J
  2. B150 ~J
  3. C350 ~J
  4. D490 ~J

Correct answer

C. 350 ~J

Step-by-step solution

For Isobaric process aligned & w = P v = nR T =100 ~J & Q = u + w & Q = F 2 nR T + nR T & ( f 2 +1 ) nR T & ( 5 2 +1 ) 100=350 ~J aligned SECTION - B
