The pressure-efect of a chemically inert carrier-gas on the nucleation rate is one of the biggest puzzles in the research of gas-liquid nucleation. Different experiments may show a positive effect a negative effect, or no effect at all, at the same experiment can show both trends for the same substance depending on temperature or for different substances at the same temperature. We show how this ambiguous pressure effect naturally arises from the competition of nonisothermal effects and pressure volume work. We are able to apparently contradictory experimental results and quantify the variation of the nucleation ability in the presence of an ambient gas. Molecular dynamics simulations confirm these predictions very well.
