n. the transfer of heat through the bulk movement of molecules within fluids, such as gases and liquids. Driven by density gradients resulting from temperature variations.
Examples
“The soup heats up quickly because of convection.”
“In a kitchen, a convection oven uses a fan to circulate hot air and cook food more evenly.”
“The Earth's tectonic plates are driven by slow-moving convection currents within the mantle, where heat from the core causes molten rock to rise and then cool as it nears the crust.”
Examples
simple
“The soup heats up quickly because of convection.”
contextual
“In a kitchen, a convection oven uses a fan to circulate hot air and cook food more evenly.”
complex
“The Earth's tectonic plates are driven by slow-moving convection currents within the mantle, where heat from the core causes molten rock to rise and then cool as it nears the crust.”
Usage
Often appears in the compound 'convection current' or as a modifier in 'convection oven'.
Real-World Examples
“When the AMOC is strong, that heat is circulated by ocean currents to the North Atlantic, where it is lost to the atmosphere in a process called deep ocean convection.” “At 416 nanometers, the solar surface is dominated by granules, the convection cells that carry heat from the interior.” “On Earth, most cooling happens through convection as heat transfers from a hot object into the air and is carried away as the warmer air rises.” Etymology
From Latin convectiōnem, from convectiō (“act of carrying”), from convect-, past participle stem of convehō (“to carry together”), combination of com- and vehō.
