Work done : 69.3905 J
Further explanation
An isobaric process(constant pressure), work is done by the system(A system does work on the environment) :
W = -P.ΔV
ΔV = change in volume
Given
The volume of the system from 1.55 to 0.85 L
The pressure = 0.985 atm
Required
The work
Solution
Input the value :
W = -(0.985 x (0.85 - 1.55))
W = 0.685 L.atm
1 L.atm = 101.3 J
⇒0.685 x 101.3 = 69.3905 J
