Ah yeah, I didn't mean evaporation was a chemical process, it was something in addition to that. Aside from evaporation, there are chemical processes which (for example) generate gases, which is not a phase change but a change to form a different molecule that is gaseous at the given conditions. The cool thing is that the rate of such reactions is usually dependent on the pressure.
