A gas is allowed to expand against a constant external pressure of 2.5 bar from an initial volume of 2.5 ~L to a final volume of 4.5 ~L . What is amount of work done?

Options

  1. A-375 J
  2. B-650 J
  3. C-250 J
  4. D-500 J

Correct answer

D. -500 J

Step-by-step solution

aligned W & =-P (V₂-V₁ ) & =-2.5(4.5-2.5) & =-5.0 bar - L & =-500 ~J aligned
