convection
n 1: the transfer of heat through a fluid (liquid or gas) caused
by molecular motion
2: (meteorology) the vertical movement of heat or other
properties by massive motion within the atmosphere

Convection \Con*vec"tion\, n. [L. convectio, fr. convehere to
bring together; con- vehere to carry.]
1. The act or process of conveying or transmitting.
[1913 Webster]

2. (Physics) 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.
[1913 Webster]

Liquids are generally heated by convection -- when
heat is applied from below. --Nichol.
[1913 Webster]

  • Convection - Wikipedia
    Convection, especially Rayleigh–Bénard convection, where the convecting fluid is contained by two rigid horizontal plates, is a convenient example of a pattern-forming system
  • Convection | Definition, Examples, Types, Facts | Britannica
    Convection, process by which heat is transferred by movement of a heated fluid such as air or water Natural convection results from the tendency of most fluids to expand when heated—i e , to become less dense and to rise as a result of the increased buoyancy
  • Convection - Definition, Examples, Types
    What Is Convection? Convection is the process of heat transfer within a fluid due to the movement of the fluid itself When a part of the fluid becomes warmer, it typically becomes less dense and rises, while cooler, denser fluid sinks This creates a flow that redistributes heat
  • Understanding Convective Heat Transfer: Coefficients, Formulas Examples
    Heat transfer between a solid and a moving fluid is called convection This is a short tutorial about convective heat transfer
  • Convection: Definition and Examples - Science Facts
    Convection is the heat transfer process from one region to another due to the movement of fluids like air or water The initial heat transfer occurs through conduction, but the primary transfer occurs through convection
  • Convection | Physics - Lumen Learning
    Convection is heat transfer by the macroscopic movement of mass Convection can be natural or forced and generally transfers thermal energy faster than conduction
  • Convection - CK-12 Foundation
    Convection is the transfer of thermal energy by particles moving through a fluid (either a gas or a liquid) Thermal energy is the total kinetic energy of moving particles of matter, and the transfer of thermal energy is called heat
  • Convection – The Physics Hypertextbook
    Convection is the transfer of internal energy into or out of an object by the physical movement of a surrounding fluid that transfers the internal energy along with its mass
  • 14. 6 Convection - College Physics 2e | OpenStax
    While convection is usually more complicated than conduction, we can describe convection and do some straightforward, realistic calculations of its effects Natural convection is driven by buoyant forces: hot air rises because density decreases as temperature increases
  • Convection: NOAA Physical Sciences Laboratory
    discover the secrets behind intricate cloud patterns as well as dark, ominous thunderstorms look at convection through the eyes of a NOAA scientist, and create your own computer model of convection learn about this and other displays at NOAA and how to see them for yourself!
