What is an insulator of heat?

Answer 1

Heat insulators are simply materials that don't allow heat to pass through it. Some examples of these materials are woods, glass and ceramic.

Ceramics are the most commonly used thermal (heat) insulators. Examples include the tiles that form the heat shield on the Space Shuttle.

Answer 2

well, I read in the PSLE ultimate science guide that air is the best insulator of heat and silver is the best conductor of heat. However, silver is not used as wires because it is too epensive.

Answer 3

A heat insulater is a materail that conducts heat e.g metal.

answer 2

A heat insulator is a material that will not allow (or at last inhibit) the transfer of heat from one place to another. A highly reflective foil can be used for this. [A vacuum flask relies on the fact that heat will not be conducted/convected through a vacuum. But the heat may be radiated, hence the reflective/mirror surfaces to prevent radiation.]

Otherwise, heat insulators, more commonly called thermal insulators, are usually made of fine fibres to trap air, as air is a poor conductor of heat. examples would be fibreglass, wool, eider down.

If High temperature is the problem, then the thermal insulator will be required to withstand that extra challenge. materials here could include mica sheet, asbestos or other high temperature glass-like fibres, and many ceramic materials. Graphite pots are sometimes used for very hot liquids, as are refractory ceramics.

Answer 4

An object, such as a blanket or a fur coat, that tends to slow down or reduce the rate at which heat is transferred from one object to another.

Answer 5

Heat insulators include materials used to reduce the rate of heat transfer, or the methods and processes used to reduce heat transfer and cloth.

Answer 6

i think that the best insulator of heat is Polystyrene...

Answer 7

a heat insulator is a material with a high capacity and obviously n high melting point

the best materials for this use is a ceramic

Answer 8

duck feathers

Answer 9

An object such as a fur coat or a blanket
