FREE Expert Solution

Recall that work (w) is given by:

w=-PΔV

where:

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)
