Convection is defined in the related link. It requires molecular movement to carry the heat away. The exposed surface of a radiator is hot and in contact with air. The air molecules, when in contact with the surface, pick up heat energy and move away, carrying the heat with them -- hence, convection.
=============================
What else can I help you with?
A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
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.
What do you need for convection to occur?
Convection occurs when there is a difference in temperature that causes a fluid (liquid or gas) to move. This movement is driven by the warmer, less dense fluid rising and the cooler, denser fluid sinking. The presence of gravity is also essential for convection to occur.
Where do convection work best?
Convection works best in fluids like air and water, where temperature differences lead to density variations and create fluid motion. It is commonly seen in the Earth's atmosphere, oceans, and in heating systems like radiators and hot air balloons.
What uses convection?
Lava lamps and hot air balloons
What are the applications of convection?
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.

What is more likely to occur in the water thermal energy transfer by conduction or convection?
Convection
What two states of matter can occur in convection?
Convection currents are in the liquid and gas states.
How does convection take place in your boiler?
In a boiler, convection occurs when heated water or steam rises naturally due to its lower density, creating a convection current. This helps to transfer heat from the combustion gases to the circulating water or steam. The heated water or steam then moves towards the radiators or other heat transfer surfaces, releasing heat and cooling down to create a continuous cycle of convection.
In which layer of earth does convection occur?
mantle
What types of matter does convection occur?
Convection occurs mainly in the gaseous state, where heat is transferred through currents in air. Convection can also occur in liquids, however it is generally identified with gases.gas and liquid
Where can a divergent boundary occur?
They occur when the convection currents are less dense and rise.
