ome session.masteringchemistry.com 20 of 2 Part A A piston has an external pressure of 12.0 atm. How much work has been done in joules if the cylinder goes from a volume of 0.120 liters to 0.540 liters? Express your answer with the appropriate units.

Solution

w = p (V₂-V₁) = 12.0 x (0.540 - 0.120) L atm = 12.0 (0.42) L atm = 5.04 L atm

Since, we know that:

1 L atm = 101.33 J

So, w = 5.04 L atm = 101.33 x 5.04 J = 510.7032 J = 5.11 x 10² J
