Convection
I'll tell you all i know ;) convection is the heat transfer through atoms or molecules that move, so that's liquids or gases. It's difficult to see in gases, it just kind of, happens. If you turn a radiator is turned on and the room is full of cool air, the radiator in the middle will warm up the particles above it and as warm things rise these heated particles will rise, pushing the cool air towards the radiator to be heated too.

This hot air will now have lower density than the other cold air, so it will move toward the ceiling of the room and spread out, forcing more cold air to contact the radiator. This circulation and heating continues until all the air in the room is the same temperature.

The most efficient location for a radiator is underneath a window. This is because the air near the window(and the air leaking in from the window) will be cold, and will therefore drop down to the floor because cold air is heavier than warm air. On its way towards the floor the cold air will pass near the radiator where it will be warmed up, and afterwards rise towards the ceiling of the room. When the air eventually cools down it will drop to the floor, where it eventually will be heated again by the radiator. The air will continue to rotate in this manner.
In older buildings the radiator was placed near the center of the apartment, as this was where fireplaces were previously situated. However this proved ineffective as the cold air seeping in from the windows would have to cross the floor to reach the radiator and be heated, resulting in a very cold floor.

How does heat from a radiator transfer?
The heat energy from the radiator transfers that energy to the air molecules next to it. Those molecules then transfer that heat energy to the molecules next to them. This process continues until all the molecules are at the same energy level. This process is call conduction.
Why would a radiator transfer heat quicker to a metal spoon in contact than to the air surrounding?
Because metals a good conducors of heat
Body heat tranferred to the air by what?
The body transfer heat to air by a heat transfer method called radiation.
Why does putting foil behind radiotors reduce heat transfer?
The foil reflects the heat back to the radiator thus reducing convection off of the radiator.
What does a radiator do?
In your car, the radiator transfers its heat to the surroundings - the air. [Strictly, this is conduction, but don't quibble. This is mechanic talk.] In your room, the radiator does radiate heat into the room.
What is the radiator's job is?
the radiator's job is to transfer heat to air that passes through the radiator. pasta master (novanet)
Liquid to air heat transfer device in car?
That would be the radiator and heater core.
How is heat transferred through a radiator?
Convection, which is the transfer of heat by thermal currents in the air (or other medium)

What is a radiator used for?
To transfer heat.
What is exchange heat?
A Heat Exchanger is a device which is used to transfer heat from one medium to other. A common example is the radiator in an automobile, which transfers the heat from the liquid engine coolant to the air pulled through the radiator by the fan.

Because metals a good conducors of heat
Why does a car radiator transfer heat to it's surroundings?
'Heat' is defined as 'energy in transit from a warmer body to a cooler body'. Since a radiator is at a higher temperature than the surrounding air, energy is transfered from the ratiator to its surroundings by heat transfer. And it's "its", not"it's"! "It's" means "it is".
What heat transfer processes change air temperature?
Convection is the heat transfer through atoms or molecules that move, so that's liquids or gases. If you turn a radiator is turned on and the room is full of cool air, the radiator in the middle will warm up the particles above it and as warm things rise these heated particles will rise, pushing the cool air towards the radiator to be heated too.
How does the pully driven fan cool your car?
The fan directs air flow through the radiator so heat energy can transfer from the coolant in the radiator into the atmosphere.
Why is it necessary to remove heat from engine?
Heat can be removed from engine in three different ways. · Conduction : transfer of heat through solid · Convection : heat transfer by movement of molecules of substance · Radiation : transfer across spaces as rays such as use of fins. But, in internal combustion engine, usually heat is removed by passing coolant through air passages around engine blocks through radiator which absorb the heat by air passing over the fins and through radiator core. Air flow is assisted by Fans
