Usually, electrical conductors have loosely bound electrons. Most metals are excellent electric conductors. The element that is the best electrical conductor is silver. Liquids that contain ions also conduct electricity. These include salt solutions, acids, and bases. 1. Silver 2. Copper 3. Gold 4. Aluminum foil 5. Graphite 6. Steel 7. Bronze 8. Br...
Most organic materials are electric insulators because electrons aren’t as free to move in covalent bonds. Sea water contains ions and conducts electricity, but pure water is an electric insulator. Some elements are either conductors or insulators, depending on their form or allotrope. For example, carbon is either a conductor or an insulator. Grap...
Most metals conduct heatas well as electricity. But, electrical and thermal conductivity don’t always go hand-in-hand. For example, diamond is an electric insulator, but an excellent thermal conductor. Crystalline materials often conduct heat. 1. Silver 2. Gold 3. Copper 4. Diamond 5. Stainless steel 6. Aluminum 7. Beryllium oxide 8. Mica 9. Carbon...
Thermal insulators resist the flow of heat. Building and clothing materials are often insulators. Although you might expect glass to be a thermal conductor, it’s actually an insulator. Thermal insulators either contain open space in their structure or else their atoms and molecules are irregularly arranged. 1. Water 2. Polystyrene foam 3. Plastic 4...

ISBN: 978-81-224-1536-0.Wood, plastic, and many fabrics, such as wool and cotton, are good thermal insulators. Thermal insulators are good materials for keeping people warm. Clothing, carpets, and curtains are examples of everyday thermal insulators. Materials that conduct heat or electricity are known as conductors.
