Turkish - English
(Meteoroloji,Teknik) latent heat
the heat that is released or absorbed accompanying a change of state or of phase
The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure
When water evaporates, it stores energy, which is released as heat upon condensation This latent heat adds feeds the rising columns of air near the center of hurricanes, thereby transferring energy from the ocean into the storm
Heat that does not cause a temperature change
The heat (energy) absorbed or released as water changes between the gas (water vapor), the liquid (water droplets), and the solid (ice) states
Heat that cannot be detected The heat that enters a system when ice melts to form water or when water boils to form steam is latent heat, because there is no change in the temperature of the system See sensible heat
heat absorbed or released during a change of water phase (from gas, liquid or solid phases) at constant temperature and pressure
the heat which is given out when gases and liquids liquefy or solidify, and which is absorbed when solids or liquids melt or evaporate
The quantity of heat absorbed or emitted, without change of temperature, during a change of state (from solid to liquid or from liquid to gas) of a unit mass of a material It is a hidden heat (i e it can't be sensed by humans) that doesn't occur until phase changes ocur An example is the evaporation of liquid water cloud droplets cooling the air by removing heat and storing it as latent heat Phase changes that cool the air are vaporization (liquid to vapor), melting (solid ice to liquid) and sublimation (solid to vapor), while phase changes in the opposite direction that warm the air are condensation (vapor to liquid), fusion (liquid to solid) and deposition (vapor to ice) The latent heat is for condensation or evaporation, for fusion or melting, and for deposition or sublimation, with the sign depending on the direction of the change
The quantity of heat absorbed or released by a substance undergoing a change of state, such as ice changing to water or water to steam, at constant temperature and pressure. Also called heat of transformation. Characteristic amount of energy absorbed or released by a substance during a change in physical state that occurs without a change in temperature. Heat of fusion is the latent heat associated with melting a solid or freezing a liquid. Heat of vaporization is the latent heat associated with vapourizing a liquid or condensing (see condensation) a vapour. For example, when water reaches its boiling point and is kept boiling, it remains at that temperature until it has all evaporated; all the heat added to the water is absorbed as latent heat of vaporization and is carried away by the escaping vapour molecules
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)
the thermal energy absorbed or released when a material experiences a phase change
The energy absorbed or released during a change of state
The heat energy needed to change the state of a substance (i e : from a liquid to a gas) but not it's temperature
The amount of heat needed to convert one pound of water to one pound of steam Latent heat is expressed in BTU per pound
The heat energy that must be absorbed when a substance changes from solid to liquid or liquid to gas, and which is released when a gas condenses or a liquid solidifies
Energy transferred from the earth's surface to the atmosphere through the evaporation and condensation processes (Source: Carbon Dioxide Information Analysis Center, 1990)
The energy released or absorbed during a change of state Examples include condensation and sublimation
amount of heat required to change a substance into a new state; heat that does not affect body temperature
heat that is stored as water molecules evaporate and become water vapor The heat is released when the water vapor condenses back to a liquid
