conductors transfer thermal heat
The rate of transfer of thermal energy through a material is called its thermal conductivity, and it's different for different materials. However, that measures heat transfer, and heat and temperature are related but distinct concepts. Basically: there is no answer to the question, because scientifically there is no such thing as the "speed" of a temperature.
Yes, depending on what material it's made of, it would have a different coefficient of thermal expansion. Materials expand with heat.
Examples: density, melting point, boiling point, thermal conductivity, resistance to corrosion, etc.
The movement of heat through a solid is called heat conduction.
ThermalsXD
Materials that transfer thermal energy well are called good themal conductors. The metals are generally good conductors of heat (thermal energy).
Fluid.
Convection
Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
conductors transfer thermal heat
An insulator is a material that does not allow a transfer of electricity or heat energy. Materials that are poor thermal conductors can also be described as being good thermal insulators. Feather, fur, and natural fibers are all examples of natural insulators
E. A. Allcut has written: 'An analysis of heat transfer through thermal insulating materials'
All materials have thermal properties.
Thermal energy exists in materials raised to a high temperature, because they can then transfer this energy to materials at lower temperatures. For example , heating radiators transfer energy to the building they are in. Electric energy is basically the movement of free electrons in a conductor, which can then do work such as turn an electric motor, or indeed produce thermal energy in a heating element,
Electrical contact materials used in switches brushes and relays must possess high thermal conductivity and high melting point.High thermal conductivity dissipates heat effectively and high melting point is to avoid fusing in case of accidental overheating.
Good insulation materials have high thermal resistance, low thermal conductivity, durability, and are non-toxic. They should effectively reduce heat transfer and be resistant to moisture and fire.
