Sensible heat is heat energy that is transported by a body that has a temperature higher than its surroundings via conduction, convection, or both. Sensible heat is the product of the body's mass, its specific heat capacity and its temperature above (an inferred) reference temperature. In physics, heat, symbolized by Q, is defined as energy in transit. ... In thermodynamics, temperature is the physical property of a system that underlies the common notions of hot and cold —something that is hotter has the greater temperature. ...

In the atmosphere, large-scale transport of heat from the tropics to the poles is affected by both 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, the latter of which is associated with the phase changes of atmospheric water vapor, mostly vaporization and condensation.

The tropics are the geographic region of the Earth centered on the equator and limited in latitude by the two tropics: the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. ... This article or section does not cite its references or sources. ... The CYCLONE, an early computer built in 1959 by Iowa State University, was based on the Institute for Advanced Study (IAS) architecture developed by John von Neumann. ... This article needs cleanup. ... In its most common usage, the term phase change indicates that a substance has changed among the three classical phases of matter: solid, liquid and gas. ... Water vapor or water vapour, also aqueous vapour, is the gas phase of water. ... Evaporation is the process whereby atoms or molecules in a liquid state (or solid state if the substance sublimes) gain sufficient energy to enter the gaseous state. ... Condensation is the change in matter1 of a substance to a denser phase, such as a puppy gas (or vapor) to a liquid. ...

Heat added or removed, which can be measured by a change of temperature of a fluid substance.
