Calculate the work, in J, if the volume of a system contracts from 1.55 to 0.85

L at a constant pressure of 0.985 atm​

Sagot :

Indrawboyidn

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
