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.

How do insulators slow down heat transfer?
They stop the hot particles from escaping into the atmosphere
Does wood transfer heat slow or fast?
slowly
What can slow the movement of heat energy from a warmer object to a cooler object?
Transfer of heat can be slow down by increase insulation. For radiation heat transfer, colour coating could reduce rate of radiation in the same manner as insulation. Reduce surface area of heat transfer (or area of contact) can also reduce rate of heat transfer.
Is the heat transferred from a hot zinc roof to a person below it a good example of heat transfer by radiation Explain?
Yes - this should be a good example of heat transfer by radiation. It is unlikely you will transfer heat by natural convection since the roof is above the person and any heated air will rise to the roof rather than sink from the roof down to the person. Air is a rather poor conductor of heat so any heat transfer by conduction from the roof down to the person will be very slow. In contrast to this, the tin roof, if hot enough will be a fairly good heat radiator - enough that it could be sensed by a person below, i.e. they will feel the radiant heat transfer.
How does friction help a car slow down?
Friction is suppose to slow down things and yes it can. HOW DOES: both 2 surfaces collide with each other, causing heat. Heat will slow down the object by "meeting" with the 2 surfaces. I hope I helped :)
How do insulators slow down heat transfer?
They stop the hot particles from escaping into the atmosphere
Does Styrofoam cups keep hot drinks hot or cold drinks cold?
A Styrofoam cup will do both. The Styrofoam is an insulator, and, as such, it slows the transfer of heat between the system (the drink) and the surroundings (everything outside the cup) If it is a cold drink, heat moves very slowly through the cup toward the drink. If it is a hot drink, heat moves very slowly through the cup toward the surrounding air.
What is the purpose of a thermal barrier?
To stop or slow down the transfer of heat from one object to another.
What materials insulates to slow down the melting process?
Styrofoam.
What does the heat shield do?
Their usually function is to slow the transfer of heat.
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
Why do particles from a cooled hot drink slow down?
That simply means that the lid will reduce the heat transfer.
Do slow movements of mantle rock called convection transfer heat in the mantle?
Yes. It's true that slow movements of mantle rock called convection transfer heat in the mantle

What type of heat transfer does adding insulation slow down?
Generally speaking, insulation slows the movement of thermal energy by convection. The dead air spaces in fiberglass insulation make it a good bet to put in walls and under roof spaces. Styrofoam coolers work because the many, many tiny air spaces in the styrofoam are places where air is trapped, and those are dead air spaces.
What is the slow down of an animals life activities during the dry season?
i think it is the HEAT,the heat slow down the animals
