Calculate the final volume of an ideal gas which expands against a constant pressure of (3.039 X 10^5) Nm^-2 from a volume 18 dm3. The work involved in the process is (2.027 X 10^3)

Answer 1

At constant pressure,

W = PΔV = P(V₂ - V₁) ⇒

V₂ = W/P + V₁

You know the work W, the initial volume V₁, and the pressure P. Plug in the numbers in appropriate units and get the final volume V₂.
