Heat of vaporization - Heat of vaporization The Heat of vaporization is the heat required to vaporize one mass unit (one gram) of a substance at its normal boiling point. The vaporization heat of water is 600 Calories per gram. Heat of vaporization is equal and opposite to its heat of condensation, any particular substance has a specific heat of condensation.

Sensible heat - Sensible heat Sensible heat is heat that is transported by a body that has a temperature higher than its surroundings. In the atmosphere, large-scale transport of heat from the tropics to the poles is effected both by sensible and latent heat, the first of which is the poleward motion of warm air and equatorward motion of cold air, primarily driven by the cyclonic mixing taking place in the Ferrel cell in the midlatitudes and the latter of which is associated with the phase changes of atmospheric water vapor, mostly vaporization and condensation..

Fire - of combustible gases ejected from a fuel. It starts by subjecting the fuel to heat or another energy source, e.g. a match or lighter, and is sustained by the further release of heat energy. Controlling fire was one of humankind's first great achievements and made possible migration to colder climes which otherwise would have remained out of reach for colonization. Fires and burning have often been used in religious sacrifices, as the smoke of the fire disperses into the heavens. Fire is one of the four classical elements, as well as one of the five Chinese elements. The burning of wood is often the first association to the word fire, and trees have since ancient times supplied much of the energy needed by humans. In the past, metal smelting and charcoal.
