yes and hot too. Insulation is a heat barrier -- it tries to prevent heat exchange between the two sides. Vacuum is the best. Then air. Metals are the worst. ====================
Styrofoam is used to keep drinks cold or warm.
Yes, because it does not conduct heat.
This is because tin is an excellent conductor of heat, meaning, heat passes right through it. So if you are trying to keep something hot from getting cold, the heat will escape and if you are trying to keep something cold from melting then heat will get in and melt it.
In general, foam is a better insulator than metal, and so foam would be expected to keep water hotter longer under most normal circumstances.

In the summer they keep it cool and when it is cold it acts like an insulator.
Things which keep warm things warm and cold things cold are referred to as insulators.
Wetsuits are a great example of how water is an insulator. when the wet suit gets wet, it puts a thin layer of water between the suit and your skin. This layer of water keeps your body heat in, and the cold water out.
A thermal insulator is totally incapable of answering this question
yes it is. its keep the cold in and the hot air outside and vice versa.
Yes it would as insulators keep in the heat and keep it out depending on whether the item is hot or cold.
Newspaper is a good heat/cold insulator. In England they are traditional for keeping fish 'n chips warm
Because there is lots of air pockets, and air is an excellent insulator so it keeps the cold inside the bottle.
A water pitcher with a built-in filter is a good option for keeping water cold and easily accessible in the fridge.
Fur is a good insulator and protects them against the cold.
yes, wood is an insulator so it keeps things warm.
