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.


Why is a vacuum a better insulator than air?

A vacuum is a better insulator than air because it lacks particles to conduct heat through conduction or convection. Without particles present, heat transfer is limited to radiation, which is less efficient. This makes vacuums good insulators for maintaining temperature, as they prevent heat loss or gain.


Is krypton a good insulator of heat and electricity?

Krypton is not a good insulator of heat or electricity, as it is a noble gas known for its low reactivity. It is typically used in lighting applications and as a gas insulator in certain types of windows. For better insulating properties, materials like glass, rubber, and ceramics are typically used.


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.


Is a vacuum a good insulator?

No, a vacuum is not a good insulator. While it can slow down heat transfer through conduction and convection by eliminating air molecules that typically carry heat, it is not an effective insulator against radiant heat transfer. Materials like foam, fiberglass, or mineral wool are better insulators due to their ability to trap air in small spaces.

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.


How are porous materials used as thermal insulators?

actually the insulator is the dead air in the pores a better insulator is vacuum (only radiation) air has conduction convection and radiation air is easier to handle near sea level

Which is the better thermal insulator saw dust or styrofoam?

saw dust is the better termal insulator


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.

Why put argon gas in windows?

Argon gas is added between window panes to improve insulation by reducing heat transfer. It is a better insulator than air, helping to enhance the energy efficiency of the window and reduce energy costs.


How do you use insulator in a sentence?

That wire could use a better insulator.


Is bubble wrap or plastic wrap a better insulator?

It is an insulator. It would take many wraps to make it become a good insulator. There are much better products in the market place to use for insulation purposes which are much safer.
