Conduction vs. Convection — What's the Difference?

The transmission or conveying of something through a medium or passage, especially the transmission of electric charge or heat through a conducting medium without perceptible motion of the medium itself.

Convection is single or multiphase fluid flow that occurs spontaneously due to the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity (see buoyancy). When the cause of the convection is unspecified, convection due to the effects of thermal expansion and buoyancy can be assumed.

(physics) The conveying of heat or electricity through material.

The act or process of conveying; transmission.

The act of leading or guiding.

Heat transfer in a gas or liquid by the circulation of currents from one region to another.

(obsolete) The act of training up.

Fluid motion caused by an external force such as gravity.

The act of leading or guiding.

(Meteorology)The transfer of heat or other atmospheric properties by massive motion within the atmosphere, especially by such motion directed upward.

The act of training up.

(obsolete) The process of conveying something.

Transmission through, or by means of, a conductor; also, conductivity.

(physics) The transmission of heat in a fluid by the circulation of currents.

The transmission of heat or electricity or sound

(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.

The act or process of conveying or transmitting.

A process of transfer or transmission, as of heat or electricity, by means of currents in liquids or gases, resulting from changes of temperature and other causes.

The transfer of heat through a fluid (liquid or gas) caused by molecular motion

(meteorology) the vertical movement of heat or other properties by massive motion within the atmosphere
