We’re being asked to calculate the work for a system that has an initial volume of 0.90 L to a final volume of 5.88 L against an external pressure of 1.0 atm.
Recall that work (w) is given by:
P = pressure (in atm)
ΔV = Vfinal – Vinitial = change in volume (in L)
A 100-W lightbulb is placed in a cylinder equipped with a moveable piston. The lightbulb is turned on for 0.020 hour, and the assembly expands from an initial volume of 0.90 L to a final volume of 5.88 L against an external pressure of 1.0 atm.
