Why is fixing aluminum foil to the wall behind a radiator reduces energy transfer through the wall?

Some of the heat that would be absorbed by the wall and lost, is reflected back into the room, keeping the room warmer.

Why does opaque clothing reduce the transfer of heat by radiation?
it reduces the amount lost through holes in the clothing.
Why does the number of cooling fins affect the rate of energy transfer from the radiator?
Because the more coolant passed through the fins, the more energy can be emitted.
How does cavity wall insulation reduce energy transfer?
Cavity wall insulation is the addition of an insulating material between two layers of wall on the outside of a building. It reduces energy transfer by preventing heat (from the inside or the outside) from travelling through the wall to surrounding air.
Cooled liquid leaving the radiator travels through the?
Lower radiator hose.
What kind of matter can light transfer through?
It can transfer through transparent or translucent matter.
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)
Why does opaque clothing reduce the transfer of heat by radiation?
it reduces the amount lost through holes in the clothing.
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.
How is heat transferred through a radiator?
Convection, which is the transfer of heat by thermal currents in the air (or other medium)
Which is better for engine cooling aluminum or silicone piping?
If the problem is to help engine cooling through the direct transfer of heat out of the piping, the aluminum will be superior to the silicone piping by far. Aluminum is one of the best materials for the conduction of heat.
What is the function of a car radiator?
A radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan. Most modern cars use aluminum radiators. These radiators are made by brazing thin aluminum fins to flattened aluminum tubes. The coolant flows from the inlet to the outlet through many tubes mounted in a parallel arrangement. The fins conduct the heat from the tubes and transfer it to the air flowing through the radiator. The tubes sometimes have a type of fin inserted into them called a turbulator, which increases the turbulence of the fluid flowing through the tubes. If the fluid flowed very smoothly through the tubes, only the fluid actually touching the tubes would be cooled directly. The amount of heat transferred to the tubes from the fluid running through them depends on the difference in temperature between the tube and the fluid touching it. So if the fluid that is in contact with the tube cools down quickly, less heat will be transferred. By creating turbulence inside the tube, all of the fluid mixes together, keeping the temperature of the fluid touching the tubes up so that more heat can be extracted, and all of the fluid inside the tube is used effectively. Radiators usually have a tank on each side, and inside the tank is a transmission cooler. The transmission cooler is like a radiator within a radiator, except instead of exchanging heat with the air, the oil exchanges heat with the coolant in the radiator. This helps to remove heat from the transmission.
Which type of heat transfer does an oven mitt reduce?
An oven mitt reduces heat transfer through conduction. Because oven mitts are usually made of materials that are poor conductors of heat, the transfer of heat from the hot object to your hand is reduced when wearing them.
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

Because the more coolant passed through the fins, the more energy can be emitted.
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.
