Because air is a very low density material, there are not a lot of atoms per unit volume to engage in heat transfer type collisions, and if the air is trapped and therefore motionless, it does not carry heat away with it by moving to another location.

What stops the flow of electricity?
Turn off the switch, generator runs out of fuel, wind not turning the windmill, solar panel at night, diode, insulation.
What are mica products?
A: Mica is an insulator used extensively in capacitors and hi quality transformers. It has very good temperature coefficient
What does an insulator do to electrical current?
It stops the flow of the electrical current.
What is the duration of Trapped by the Mormons?
The duration of Trapped in the Closet is 1.52 hours.
What is the duration of Trapped by Television?
The duration of Trapped by Television is 1.07 hours.
What TA make a good insulator?
Trapped air makes a good insulator.
What makes something a good insulator?
Trapped air makes a good insulator.
Is coal a insulator?
Yes, because it has lots of trapped air in it and that's what makes a good insulator.
Trapped air is a good what because it reduces heat transfer?
Insulator.
Why is fiberglass used to insulate wooden buildings?
Air is an excellent insulator. Fiberglass is a good insulator because of the vast amount of air spaces trapped in it.
How do you make a good insulator?
the insulator s metal must has fully filled orbital without any free electron
Which methods of insulation use trapped air as an insulator?
A goose down jacket. Air gets trapped in between the goose feathers and acts as an insulator.
Why is fiberglass a good heat insulator?
materials such as fibreglass are good insulators because they contain pockets of trapped air. :)
Why is cotton-wool a good insulator?
It has lots of air trapped between its fibres. Air itself is a good insulator, so trapped air is going to prevent heat transfer. Cotton is a very good insulator as long as it stays dry. There are thousands of tiny air spaces between the fibers that slow the transmission of heat or cold. That is why jackets or even T-shirts feel like good protection from the cold when outside.
Why is wadding or filling a good insulater?
Wadding, or filling, will trap pockets of air. As the air is trapped, it cannot convect heat so easily, and it is also more difficult for heat to be conducted. So, trapped air is a good insulator.
Which makes a good insulator?
Trapped air is the best, like a thermal flask. Water is pretty good, as well as fabrics in some clothes.
Is sponge a good heat insulator?
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
