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 does putting foil behind radiotors reduce heat transfer?
The foil reflects the heat back to the radiator thus reducing convection off of the radiator.
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
How does silver coating on surfaces of glass walls minimise heat transfer?
being a poor radiator,the two silver faces reflects heat back and forth and reduce heat by radiation.
Why is A radiator is not a good name for a heater of that name because?
this is because the major heat transfer in it, is convection.and it is better to name it convector.
Is white surface good radiator of heat?
A white surface is a good radiator of heat.
What is a radiator used for?
To transfer heat.
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)
What property is required of a car radiator?
The ability to transfer heat energy.
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.
Is a radiator a insulator?
The purpose of a radiator is to transfer heat as quickly as possible. It is pretty much the opposite of an insulator.
What is the purpose of fins in the radiator core?
To speed up the transfer of heat energy.
How is heat transferred through a radiator?
Convection, which is the transfer of heat by thermal currents in the air (or other medium)
Liquid to air heat transfer device in car?
That would be the radiator and heater core.
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.
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".
Why is a car radiator made of aluminum?
The purpose of a radiator is to transfer heat from the engine to the atmosphere, so radiators need to be made of a material with a high heat transfer coefficient. Aluminum has a high heat transfer coefficient. In other words, aluminum conducts heat very well. There are other materials, such as copper, which conduct even better, but aluminum is more economical to use than copper.
When does Heat transfer occurs in liquid and gasses?
Heat transfer occurs whenever two or more objects of different temperatures are in contact with each other. Spilling hot water on yourself causes heat transfer from the water to you. When you drive your car the hot engine and radiator transfer heat to the surrounding air in order to cool the engine.
