diffusion | convection |
the act of diffusing or dispersing something, or the property of being diffused or dispersed; dispersion
(physics) the scattering of light by reflection from a rough surface, or by passage through a translucent medium
(physics) the intermingling of the molecules of a fluid due to random thermal agitation
the spread of cultural or linguistic practices, or social institutions, in one or more communities
(physics, weather) Exchange of airborne media between regions in space in an apparently random motion of a small scale.
the movement of water vapor from regions of high concentration (high water vapor pressure) toward regions of lower concentration.
The process of conveying something.
(physics) The transmission of heat in a fluid or gas by the circulation of currents.
(meteorology) The vertical movement of heat and moisture, especially by updrafts and downdrafts in an unstable air mass. The terms convection and thunderstorm are often used interchangeably, although thunderstorms are only one form of convection. Towering cumulus clouds are visible forms of convection.
