The work done during expansion of a gas from a volume of 4 dm ^3 to 6 dm ^3 against a constant external pressure of 3 ~atm is (1 ~L ~atm =101.32 ~J ) :

Options

  1. A-6 ~J
  2. B-608 ~J
  3. C+304 ~J
  4. D-304 ~J

Correct answer

B. -608 ~J

Step-by-step solution

Work =-P_ e x t volume change aligned & =3 101.32 (6-4) & =6 101.32 & =-607.92 ~J =-608 ~J aligned
