convection, definition of


Physics. the transfer of heat by the circulation or movement of the heated parts of a liquid or gas.

Often encountered by people the most when heating a home, as the heat rises to the ceiling. The opposite effect, cooling, can be observed near windows on a cold night, the windows cool the air and it drops. Therefore convection often causes drastic heat loss close to windows. If not dealt with (by the usage of curtains or double glazing usually) this can contribute greatly to heating and cooling costs, as in Summer you will get the opposite effect of heat easily entering the property from the outside via the glass & convection.
