Is Cool boxes an insulator or conductor?
Cold boxes are thermal insulators, however with regard to electrical conductance, that depends on what they box is made of.
Why are cool boxes lined with expanded polystyrene with air bubbles in it?
Air is a poor conductor of heat. Likewise, the thin walls of the bubbles of polystyrene are poor conductors. Bubbles of air, rigidly fixed in a polystyrene matrix, cannot transfer heat by convection. That leaves reducing radiation as the only unaddressed mechanism for controlling heat loss. Its low cost and ability to be molded makes expanded polystyrene an economical choice for an effective insulator.
When thermal energy is removed from matter what happens to its temperature'?
it is hot temperature but when thermal energy leaves the temperature is cool
Why is paper a good insulator?
It creates a shield of air to keep the heat in and surrounding cool air out.
What insulation material can keep objects cool?
A vacuum is a good insulator so a "thermos" bottle will keep liquids 8or solids) cool for a while.

Are boxes cool?
boxes are really cool
Why bubble wrap is a good insulator?
It is not a good insulator if you are dealing with temperature because of the air pockets and the temperature of air inside a bubble (air pocket) but it would be a good insulator if your dealing with something related to circuits because plastic is not a conductor.
Why do people use newspaper to wrap cold food?
The newspaper is a thermal insulator - it will take heat longer to pass through the newspaper, than to pass through air. The newspaper - or any other thermal insulator - won't keep an object hot or cold indefinitely, however.The newspaper is a thermal insulator - it will take heat longer to pass through the newspaper, than to pass through air.

Is saltwater an conductor?
yes feather are cool
Why is a fabric a good insulator?
It is a good insulator because the fabric has little fibers in it to keep the cool AIR in, which means that the fabric is strong. ! :)

cool

Why are yurts useful?
In the summer they keep it cool and when it is cold it acts like an insulator.
Why will a watermelon stay cool for a longer time than sandwiches when both are removed from a cooler at the same time?
it is an excellent insulator and poor conductor of heat. it takes a lot of heat energy to change the temperature because water doesn't heat up easily.
When thermal energy is removed from matter what happens to its temperature'?
it is hot temperature but when thermal energy leaves the temperature is cool
