Recall that work (w) is given by:
P = pressure (in atm)
ΔV = Vfinal – Vinitial = change in volume (in L)
Also note that if work is:
• (+): work is done by the surroundings to the system (compression)
• (–): work is done by the system to the surroundings (expansion)
If a balloon is expanded from 0.055 L to 1.403 L against an external pressure of 1.02 atm, how many L⋅atm of work is done?
a) 0.056 L⋅atm
b) -1.37 L⋅atm
c) 1.43 L⋅atm
d) 1.49 L⋅atm
e) 1.39 L⋅atm
