Convection is a way to transfer heat. When something is heated, by flame, for example, the air right above the flame will expand [as substances expand when heated]. This expansion will cause it to have a greater volume. The air will have the same mass, so its density will decrease as density is mass over volume. Because its density decreases, it will rise. Once risen, it will do the opposite: lose the energy by cooling, decrease in volume, increasing the density, and fall back down.
What else can I help you with?
Which method is used to deliver hear in most central heating system?
Convection
Why do so-called radiators which are part of central heating system have wrong name?
Radiators in a central heating system give off heat through radiation, convection, and conduction. While they primarily rely on convection to warm a room, they are named after the radiation method of heat transfer. It's a historical naming convention that has stuck over time.
Is heating of air touching a hot surface conduction or convection?
convection
What are the differences between infrared and convection heating methods?
Infrared heating uses electromagnetic waves to directly heat objects, while convection heating relies on the circulation of air to transfer heat. Infrared heating is more efficient and heats up quickly, while convection heating is slower but provides more even heating throughout a space.
What are the servicios performed by a central heating?
The service performed by central heating itself is heating a home or building. A central heating service or company can provide repairs or installation of central heating units.
Heating food under a heating lamp is an example of heat transfer by?
convection
Most of the heating of the troposphere is caused by?
Convection
What do you use convection for?
Heating structures, cooking.
How do fireplaces use convection?
heating the air
What are the methods of heating?
conduction, convection, and radiation
Is glider use natural convection or create by itself convection by using any heating meterialial?
it uses natural convection
Is the sun heating they earth the best example of convection?
The heating alone is not, no, but the convection it sets up, thus forming winds and weather systems, is a valid example.
