WebJan 17, 2024 · By free expansion, I am referring to gas allowed to expand freely against vacuum in a Joule Expansion. If gas is ideal then change in Internal Energy '∆U' and change in Enthalpy '∆H' is zero. (By ∆H = ∆U + nR∆T). But I was wondering whether '∆H' would still be zero for real gas? (I know that ∆U will be zero for real gas. WebMay 7, 2015 · "One mole of ideal gas initially at a pressure of 1 atmosphere and T = 298 K, is expanded into a volume 50% larger adiabatically."
