Calculate the work associated with the expansion of a gas
from46l to64 l at
a constant external pressure of 15 atm?

Initial volume (Vi) : 46 L Final volume (Vf) : 64 L External pressure (P) : 15 atm
We can find the work (w) associated with the expansion of a gas using the following expression.
w = - P. ΔV
w = - P. (Vf - Vi)
w = - 15 atm. (64 L - 46 L)
w = - 270 atm. L. (101.325 J / 1 atm. L)
w = - 2.7 * 10⁴ J
w = - 27 kJ
