3.3: Phase Diagram for Water Vapor - Geosciences LibreTexts

WebLet's see. 4 times 200 is 800, 800 times 100; yeah, that's about right. Now, we're dealing with 100 degree water vapor, and we have to turn that 100 degree water vapor to 110 degree vapor. So we use the specific heat of vapor. 1.89 joules per gram Kelvin. Multiplied by the amount of vapor we're dealing with, 200 grams. WebThe latent heat of sublimation is the amount of heat gained by a substance to convert its phase from solid to vapor or it is heat rejected by a substance while converting its phase from vapor to solid. Sublimation indicates the transition of the phase of the material from solid to vapor without entering into the liquid phase.
