A gas at constant pressure 1.5 10^5 Pa changes volume from 0.004 m^3 to 0.001 m^3. The work done by the gas is:

  1. -45 J
  2. -450 J
  3. 450 J
  4. -4500 J
Answer

B) -450 J

W = pDelta V = 1.5 10^5 (0.001 - 0.004) = -450 J. (Negative: the gas is compressed, so work is done on it.) SLO P-11-C-06 · Application
