sublimation point การใช้

So the melting point given is really the sublimation point, and note the boiling point is given for a particular high pressure.
Or the at-89.2C ( cf . sublimation point of CO 2-78C ), would CO 2 precipitate from the air?
A Phase diagram is a good way to see how the phase varies with temperature and pressure, and how changing those conditions affects the melting / boiling / sublimation point.
:: : : : : : : Low gravity, leads to low pressure, which leads to a low sublimation point, which leads to a higher vapour pressure.
Evaporation, regardless of whether it is off a solid or a liquid, occurs at any temperature below the sublimation point, melting point, or boiling point, whichever is applicable at the operating pressure.
