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

Is plasticine a conductor or insulator?
Plastic is an electrical and thermal insulator.
Which of the following is the best thermal insulator APEX?
Air (Explanation): water has a high specific heat capacity, but it can boil. stone (😂) also is a good thermal insulator, but it can get really hot. Metal is a very good thermal conductor, so it is definitely not that. Therefore, air is the best (its also really hard to boil).
What material is the worst conductor of heat?
the worst conductors of heat are wood, plastic, rubber, and cloth.
Is metal the best thermal insulator?
Metal is a very poor thermal (and electrical) insulator. It is a good conductor of heat (and electricity, obviously). Copper (a metal) is one of the best thermal conductors known to man--most laptops use pieces of copper to transfer the heat from the processor and graphics chips to the heatsync (typically aluminum), where the fan can remove the heat. Materials like foam, rubber, etc. are good thermal insulators (think of pot holders...).
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.
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.
What is a very good thermal insulator?
oxygen.is the best 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.
Which is an example of a very 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.
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.
Is stone the best thermal insulator?
No, stone is not the best thermal insulator. Materials like fiberglass, foam, and cellulose are much better insulators due to their low thermal conductivity and ability to trap air pockets that reduce heat transfer. Stone is a poor insulator because it has high thermal conductivity, meaning heat can easily pass through it.

Is the best thermal insulator A. Stone Water C. Air Metal?
Air is the best thermal insulator among the options provided. Air has low thermal conductivity, meaning it is effective at trapping heat and preventing its transfer. Stone, water, and metal have higher thermal conductivities compared to air.
How does plastic act as a heat insulator?
For practical purposes, air is an excellent thermal insulator. So any material with lots of entrained air (and through which the air cannot freely pass) will be a good thermal insulator. The remaining conduction path through the material is along the filmy walls of the bubbles, and this path will be long and of small cross-section. A vacuum is of course a better thermal insulator, but there are practical difficulties in making a foam of vacuum bubbles. And there are some materials (some CFC gases) which are better thermal insulators than air, but once again there are difficulties in keeping these gases entrained in the foam bubbles.
An example of a insulator?
An insulator has several different meanings. The two most common are an electrical insulator and a thermal insulator. an electrical insulator would be polyethylene. a thermal insulator would be wool.
Which is a good thermal insulator?
The best thermal insulator is vacuum as in the gap of the thermos bottle. Another god thermal insulators is air (as in closed cell polyurethane foam or double glaze windows, or any gas in closed environment.
