How does energy transfer?
hot to cold, fast to slow, high to low.
Why does styrofoam slow down heat transfer?
Styrofoam is a type of plastic that has had a lot of air incorporated into it. This material has a lot of air spaces with trapped air throughout its volume. We have been taught that air that cannot move, like air trapped in insulating strands of, say, fiberglass, will act as an insulator. The dead air cannot move and transfer thermal energy via the mechanism of covection. Styrofoam has almost countless dead air spaces within it, and it is a pretty good insulator.
Why is cotton-wool a good insulator?
It has lots of air trapped between its fibres. Air itself is a good insulator, so trapped air is going to prevent heat transfer. Cotton is a very good insulator as long as it stays dry. There are thousands of tiny air spaces between the fibers that slow the transmission of heat or cold. That is why jackets or even T-shirts feel like good protection from the cold when outside.
What is the material that slows or stops the flow of energy such as heat?
Resistance does not 'slow down' current, it limits the current.The ability of a substance to slow down current is a function of the number of charge carriers per cubic metre of that material.
Does wood transfer heat slow or fast?
slowly
How is the rate of a cooling of a building affected by the thickness and the thermal conductivity of its walls?
Generally thicker walls slow down the transfer of heat, and if the material is a good thermal conductor that will increase the rate of transfer.

Is stirafom a good insulator?
All the isolated gas bubbles slow down transfer of heat. It also helps that there is very little material to hold on to much heat so the heat that does transfer through it is very low and also There's lots of empty space in between all the bubbles and because it's so light people use it as an insulator.
Why is newspaper a good insulator?
newspaper is a good insulator because it will trap the heat in the thickness of the newspaper. it isn't always a good insulator because it can get wet and tear so therefor it will let heat out
What is the transfer of heat energy?
thermal energy. The transfer of heat happens when a warm fast moving molecule run into slow a cold ones the heat is then transferred from the warm molecule to the cold oneAnswerHeat is energy in transit from a higher temperature to a lower temperature. Heat isn't transferred; heat describes the process of transfer.

Materials through which heat can flow easily are called?
A conductor easily Transmits heat and electricity. A conductor can include: Copper, some metals, metalloids, and more. ! - The Silver Fox.
How do you describe animals'movement?

Does slow movements of mantle rock called radiation transfer heat in the mantle?
You have the mechanism of heat transfer correct but the name for it incorrect! The process where slow movements of mantle rocks transfer heat is known as convection.
Does wood transfer heat slow or fast?
slowly
