Why would a radiator transfer heat quicker to a metal spoon in contact than to the air surrounding?
The metal spoon has a higher thermal conductivity than air, which allows heat to transfer faster from the radiator to the spoon. Air is a poor conductor of heat compared to metal, so the heat transfer is more efficient when the radiator is in direct contact with the metal spoon.
What heat transfer is warming hand over a radiator?
The heat transfer that warms your hand over a radiator is primarily convection. As the air surrounding the radiator is heated, it rises, carrying heat to other surfaces such as your hand. Additionally, some heat transfer may also occur through radiation, as the hot radiator emits infrared radiation that can be absorbed by your hand.
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.
Which example of heat transfer is due mainly to convention?
Heating a room with a radiator is an example of heat transfer mainly through convection. As the air surrounding the radiator is heated, it becomes less dense and rises, creating a convection current that circulates warm air around the room.
Explain how you could feel heat from a radiator by more than one method of transfer?
You can feel heat from a radiator through conduction, where direct contact with the hot radiator causes heat to transfer from the radiator to your body. You can also feel heat through convection, where the hot air near the radiator rises, creating a current that carries heat to you.
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.

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.

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.
