A piston has an external pressure of 7.00 atm . 304.913 J work has been done in joules if the cylinder goes from a volume of 0.160 liters to 0.590 liters

work done = - P Δ V

pressure = 7 atm

v1 = 0.160 L

v2 = 0.590 L

Δ V = 0.590  - 0.160

       = 0.43 L

Work done = - 7 * 0.43

                  = - 3.01 L atm = 304.913 J
