In order for heat to be conducted, there have to be collisions between atoms or molecules, in which energy is transferred from a faster moving particle to a slower moving particle. In a vacuum there are no particles, hence, no particle collisions and no heat conduction.

Is fibreglass a better insulator than vacuum?

Vacuum is a better insulator than fiberglass. Vacuum has no particles to transfer heat through, while fiberglass relies on slowing down heat transfer through its material. This makes vacuum a more effective insulator, as it minimizes heat transfer through conduction and convection.


Which is an example of a good insulator?

it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.


Which is an example of a very good insulator?

Is vacuum an insulator or a conductor?

Vacuum is an insulator because it does not contain any charged particles that can carry an electric current. This lack of particles means that there are no free electrons to facilitate the flow of electricity, making it an effective insulator.


Why is vacuum the best thermal insulator?

Heat travels in 3 ways. Conduction, convection and radiation. Conduction is the transfer of heat through collision of particles. Convection is the transfer of heat through the movements of particles (ie. hot particle rises, cold particle sinks). Vacuum is made up of nothing (when there is no particle, it is vacuum), and so, it is unable to transfer heat through conduction and convection at all, making it the best thermal insulator


Material that doesnt allow heat to be conducted easily?

A thermal insulator. The best is a vacuum, but static air is good, if it can be contained in a mat of fibres for example.


Rank the following in order from the best conductor to the best insulator?

Copper - best conductor Glass - moderate insulator Rubber - good insulator


Is a Styrofoam cup the best thermal insulator?

No, Styrofoam is a good thermal insulator but not the best. Materials like vacuum insulated glass or foam materials with higher R-values are more effective for insulation. Styrofoam still offers decent insulation properties due to its low thermal conductivity.


Which is the best insulator?

mostly contain of all types of metal examples are coper , silver ,aluminum, and other types. you should not say gold is a good insulator it would be nice to have a gold insulator but you'd have to be very wealthy


What is a very good thermal insulator?

oxygen.is the best insulator


Is gas or a vacuum a better insulator?

A vacuum is a better insulator than gas because there are no particles in a vacuum to transfer heat through conduction or convection. Gas molecules can transfer heat through conduction and convection, making them less effective as insulators compared to a vacuum.


Is vacuum flask an insulater?

It's the vacuum that is maintained between the inner and outer containers of the vacuum flask that is the insulator. Heat is unable to move from the inner container through the vacuum to the outer container which is in contact with the outer world.
