Question

Calculate the work for the expansion of CO2 from 1.0 to 6.5 litres against pressure of 1.0 atm at constant temperature

Answer 1

557.3J is the work of expansion of the CO2 gas

Step-by-step explanation:

The work of expansion of a gas under constant temperature and pressure (Isobaric pressure) is:

W = P*ΔV

Where W is work

P is pressure = 1.0atm

ΔV = Final volume - Initial Volume = 6.5L - 1.0L = 5.5L

Replacing:

W = 1.0atm*5.5L

W = 5.5atmL

In Joules (1atmL = 101.325J):

5.5atmL * (101.325J / 1atmL) =

557.3J is the work of expansion of the CO2 gas
