Why is hollow hair a good insulator?
It insulates well for the same reason as double-pane glass: The air in the middle is a poor conductor of heat.
What insulates better aluminum or plastic?
Plastic. In general, metals are good conductors, plastics are bad conductors. You didn't specify whether you wanted heat insulation or electrical insultation, but the above applies to both.
Why is the temperatureat the top of a mountain cooler than at the bottom of the mountain?
It is cooler on top of a mountain than it is below because the sun's rays do not heat the atmosphere directly. The sun's rays bump into dust particles, splitting into different directions. therefore, as the sun ray's reach the the crust, the soil on the ground insulates more heat as it is located near the timberline where the soil insulates more heat.
What property makes a material a good insulator?
No shared electrons between neighboring atoms/molecules in the material makes for a good electric insulator.A good thermal insulator has lots of air or gas (which insulates) trapped in the material.
What insulates the body and acts as an energy reserve?
muscle
Is the American Eskimo Dog good at tolerating heat?
No, the American Eskimo Dog has a low tolerance of heat. It has a dense undercoat which insulates heat.
Why does ice wrapped in newspapers do not melt easily?
The newspaper insulates the ice from heat.
What makes an insulator insulate?
A material that insulates, especially a nonconductor of sound, heat, or electricity. A device that insulates another material or space from something. For instance glass is a good insulator from electricity. The electrons will not flow through glass. Cork is a good insulator from sound. Sound waves have a hard time passing through cork. Wood is a good insulator from heat.
Why is hollow hair a good insulator?
It insulates well for the same reason as double-pane glass: The air in the middle is a poor conductor of heat.
Is an American Eskimo Dog good at tolerating cold temperatures?
Yes, the American Eskimo Dog is good at tolerating the cold. It has a dense undercoat which insulates heat to keep it warm.
Which connective tissue insulates against heat loss?
The Adipose Connective Tissue insulates against heat loss and provides reserve fuel.
How does double glazing reduce energy loss?
It insulates the window and keeps heat in.
Fat is the most concentrated form of --- and insulates the body from heat loss?
Energy.
How does rubber stop an ice cube from melting?
It insulates it, keeping the cool in and the heat out.
Fat is the most concentrated form of and insulates the body from heat loss?
energy
Insulates against heat loss provides reserve fuel?
Subcutaneous fat deposits.
How does a down sleeping bag keep you warm?
It insulates the heat of your body temperature in the bag.
