What do conductors and insulators do?
Asked in Physics
What is the name for materials that do not allow heat to pass?
Why are materials that are good conductors of heat also poor insulators?
Is a good conductor a good insulator?
There are conductors of heat and conductors of electricity. There are also insulators of both types. The following are generally true. Good electrical conductors are bad heat insulators. They conduct heat well. Good insulators for heat are good insulators for electricity. This is because the thing that causes an electric conductor to conduct electricity well is the freedom the electrons have to move around in the conductor. When electrons are heated, the can move the heat energy around too. Electrical insulators do not have these free electrons so they do not have the extra help of the electrons in conducting heat. So, insulators of electricity don't do a great job at conducting heat. These are only general statements and there is a wide range of thermal conductivity for electrical insulators, and so you can not say anything quantitative about this general trend.
