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.

A circular flow of warmer fluid and cooler fluid is called a?
A convection current, however, this can also occur with gases.
Why are radiators put under windows?
Windows are in most situations the least insulated element of a room and therefore are the most common location for thermal bridging to occur. By placing a heat source in front of windows convection air flows insulate the internal room from radiant cooling from the window. Radiators in front of windows are in the most effective and energy efficient position in these situations.
How does heat loss occur?
It can occur through conduction, convection and radiation.
What does convection only occur in?
Convection only occurs in fluids. Fluids are gases or liquids.
In which state of water does convection occur?
nothing
What are applications of convection?
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
What are the applications of convection?
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
Radiators in central heater system transmit most heat by means of what?
convection

Where does convection occur?
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
What are convection currents and in which layer do they occur?
no
Where does convection occur on the sun?
The core
How does convection take place in your boiler?
Through cast Iron radiators and copper tubing and schedule 40 black steel piping
How does heat loss occur?
It can occur through conduction, convection and radiation.
What is more likely to occur in the water thermal energy transfer by conduction or convection?
Convection
