Question

A piston has an external pressure of 8.00 atm. How much work has been done in joules if the cylinder goes from a volume of 0.160 liters to 0.510 liters?
Express your answer with the appropriate units.

 

Answer 1

w = -P∆V

w = -(8.00 atm)(0.160 L - 0.510 L) = -(8.00 atm)(-0.35)

w = 2.80 L-atm

w = 2.80 L-atm x 101.325 J/L-atm = 284 J
