For Latent Heat we have terms and definitions in 9 topics. The topics are Atmospheric Chemistry, Climate, Climatology, Energy, Green Energy, Natural Gas, Physical Geography, Satellite Meteorology and Weather.

Latent Heat (Atmospheric Chemistry)

If a change of state occurs from gas to liquid or liquid to solid, internal energy in the form of heat is released. If a change of state occurs from solid to liquid or liquid to gas, heat is required. Different compounds absorb and release different amounts of latent heat. Water releases nearly 600 kilocalories for each kilogram of water condensed. [Journal of Applied Meteorology; v33n4; 477-489; 1994.] [A Field Guide to the Atmosphere; V. Schaefer, J. Day; page 75; 1981; Houghton Mifflin Company; Boston.] [Air, The Nature of Atmosphere and the Climate; Michael Allaby; pages 59,60; 1992; Facts on File; New York.]

Latent Heat (Climate)

Energy transferred from the earth's surface to the atmosphere through the evaporation and condensation processes.

Latent Heat (Climatology)

The heat either released or absorbed as a result of a change of state.

Latent Heat (Energy)

A change in the heat content that occurs without a corresponding change in temperature, usually accompanied by a change of state (as from liquid to vapor during evaporation).

Latent Heat (Green Energy)

Heat recovered due to difference in moisture content in two air streams.

Latent Heat (Natural Gas)

See HEAT, LATENT.

Latent Heat (Physical Geography)

Is the energy required to change a substance to a higher state of matter (solid > liquid > gas). This same energy is released from the substance when the change of state is reversed (gas > liquid > solid).

Latent Heat (Satellite Meteorology)

The amount of heat taken in or released by water when it changes phase.

Latent Heat (Weather)

The energy released or absorbed during a change of state.
