What is a good example of an insulator you can find at home?
mugs,foam cups and plastic cups
3 examples of thermal insulators?
Expanded polystyrene (packing foam) is generally considered a good heat insulator. Aerogel is considered to be one of the best insultators: You can place a Bunsen burner flame on one side of a thin slice of aerogel and your hand on the other side and not get burned.
Glass or plastic what keeps water colder?
Metal - very good conductor of heat. Not a good insulator at all (Don't wrap cans in aluminum foil.) Glass - A little better resistor of heat energy transfer but still not great. Plastic - Depending on the exact material, plastic is probably your best bet. Especially if it's a foam of some sort; the air bubbles in the foam create barriers that heat energy has to cross to be able to escape.
Is foam a good conducter of heat?
In a foam there is a large gap between the conduction band and the valence of band in the atoms makng up the foam. If any object is to conduct electricity through it the gap between the conduction band amd the valance should be minimun or overlapping so that the electrons in the valance band can go into conduction band and conduct electricity
What are good examples of heat insulators?
vacuum, styrofoam, plastic, wood, glass, rubber
What is good sound?
paper or foam cups

What are some good quality materials for a toy sword?
There are many good quality materials for a toy sword. Examples of good quality materials for a toy sword include the materials of plastic and thick foam.
Is plastic or Styrofoam the poorest conductor of heat?
The answer to this question depends on the magic word NIC. NIC is short for non-intercellular. This means that the tiny cells within the foam do not connect with each other. The foam does not soak up lots of water. You can't blow air through it. A plastic foam which is NIC is a very poor conductor of heat - a good insulator. A plastic foam which is intercellular is not a good conductor, but it is nowhere near as poor as NIC foam. Its best use is as a sponge for soaking up water.
What are some examples of a good insulator?
Examples of good insulators include rubber, glass, wood, plastic, and ceramic materials. These materials have high resistance to the flow of electricity or heat, making them effective at blocking the transfer of energy.
How can you determine if foam is a better insulator than paper?
yes you can test it under a lamp and see the temp. for the foam and paper and if one has the lowest than that's the better insulator!good luck!

Whether plastic foam which contains pockets of air would be a good conductor or a good insulator.?
Because it fills heat slowly
Examples of good heat insulator?
styrofoam ,bubble wrap ,polyurethane foam, fleece ,aluminiaum.
What does plastic feel like?
plastic feels soft and smooth =]
