There is no general speed. The efficiency of the insulator can be measured by how long the heat takes to pass through.

Is aluminum an insulator or conductor of thermal energy?

Aluminum is a conductor of thermal energy and electrical energy.


What material conducts thermal energy poorly is a?

thermal insulator


Does a good insulator prevent thermal energy from flowing through it?

Yes, a good insulator slows down the transfer of thermal energy through it. This is achieved by reducing the conduction, convection, and radiation of heat.Examples of good insulators include materials like fiberglass, foam, and ceramic.


Is glass a conductor or insulator of thermal or electrical energy?

Glass is an insulator of both energies. It does not conduct thermal energy because only it's surface warms up. It does not conduct electrical energy because its atoms do not have free electrons, which cause this process in metals.


Material that condscts thermal energy well?

a conductor does, while an insulator poorly conducts thermal energy!


Which term defines something that doesnt transfer thermal energy efficiently?

An insulator


Which term defines something that does not transfer thermal energy efficiently?

An insulator is a material that does not transfer thermal energy efficiently. It prevents heat from flowing easily through it, helping to maintain a consistent temperature on either side. Some common examples include foam, wool, and fiberglass.


A material that conducts thermal energy well is a thermal?

Something that conducts thermal energy well is a thermal...conductor. If it does not conduct well it is called an insulator.


A material that conducts thermal energy poorly?

One material that conducts thermal energy poorly is Styrofoam. This material has a low thermal conductivity due to its high concentration of trapped air pockets, which hinders the transfer of heat. This property makes Styrofoam a good insulator for keeping things cool or warm.


What is an object called if energy is not transferred through it easily?

It is called insulator. However, it must be noted for what type of energy it is to insulated (Heat or thermal energy, Electrical energy, Sound energy, Seismic or vibration energy) i.e. metal vacuum thermal insulator may not be a good electrical insulator or sound insulation may not be a suitable thermal insulation. It is to noted for the application limited such as Poly urethane is good for low temperature insulation but not good to insulate hot pipe.


What c doesn't let heat energy through it?

Ceramic is a material that doesn't allow heat energy to pass through easily. It has a low thermal conductivity, making it a good insulator.


What is another good word for thermal insulator?

An alternative term for thermal insulator is "heat insulator." It refers to a material or device that reduces the transfer of heat energy between two surfaces or objects.
