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?

Respuesta :

Work for a irreversible reaction, in thermodynamics, is calculated by multiplying the external pressure with the change in volume. Therefore,

Work = P ( V2 - V1 )
Work = 1.02 (1.403 - 0.055)
Work = 1.375 L-atm

Hope this answers the question. Have a nice day.
