Why is fiberglass a good heat insulator?
materials such as fibreglass are good insulators because they contain pockets of trapped air. :)
Why are coats good insulators?
Mainly because of the air trapped inside, in such a way that it can't move around freely.
What three materials that use trapped air to make good insulators?

Why are things with a low density good insulators?
A good insulator is a substance that does not allow energy to flow very quickly when there is a temperature difference between two areas. The most important component of good insulators is stationary air because air is a poor conductor of heat. Good insulators contain millions of tiny air spaces, which slow heat conduction through them. Thus, the heat is "kept in" or "kept out". Insulators with a lower density means there is space between the particles/molecules of the material. Having the right density is critical in whether a material makes a good insulator or not. If there is not enough density, air will flow too quickly through the material; if the density is too high no air will be trapped in the material and cool air will flow quickly to the other side.
Why are feathers good insulators?
Feathers are good insulators because they trap air. Motionless air is a very good insulator.

Is ceramics a good heat conductor?
Ceramics are good insulators. They keep heat well because they have a lot of air trapped in them.

Are feathers good insulators?
Yes, feathers are excellent insulators because of their structure - they trap air between the filaments, creating a barrier to heat transfer. This property helps birds regulate their body temperature and keep warm in cold environments. Feathers are also commonly used in bedding and clothing to provide insulation for humans.

What feature of double-glazed windows makes them good insulators?
The air, known as dead air, is what makes double glazed windows more insulated. This air gets trapped between the pains, not allowing hot or cold air to transfer.
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
Are materials containing air usually good insulators?
