Is metal a good thermal conductor
Witryna24 lis 2024 · As temperature increases, atoms and their electrons gain energy. Some insulators like glass are poor conductors when cool but good conductors when hot; most metals are better conductors … WitrynaMetals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. These conductive properties are rated based on a “coefficient” which is measured relative to silver. Which is not a bad conductor of heat? Detailed Solution.
