While a conductor transmits energy, an insulator slows or stops its passage. Some materials can be both a conductor and an insulator at the same time for different forms of energy. For example, most diamonds conduct heatexceptionally well, yet they are electrical insulators. Metals conduct heat, electricity, and sound.
Electrical conductors transmit electrical charge in one or more directions. Any charged particle may be transmitted, however, since electrons surround atoms, while protons are usually bound within the nucleus, it's much more common for electrons to move than protons. Either positive or negative charged ionsalso can transfer charge, as in seawater. ...
Most metals are also excellent thermal conductors. Thermal conductivity is heat transfer. This occurs when subatomic particles, atoms, or molecules gain kinetic energyand collide with each other. Thermal conduction always moves in the direction of highest to lowest heat (hot to cold) and depends not only on the nature of the material but also on th...
Transmission of sound through a material depends on the density of the matter because sound waves require a medium to travel. So, higher density substances are better sound conductors than low-density materials. A vacuum cannot transfer sound at all. Examples of good sound conductors include: 1. Lead 2. Steel 3. Concrete Examples of poor sound cond...

Separate these objects into conductors and insulators. Explain how you know if a material is a conductor or an insulator. Why are conductors often surrounded by an insulator for safety...
Sep 20, 2020 · Materials that conduct electrons, protons, or ions are electrical conductors. They conduct electricity. Materials that conduct heat are thermal conductors. Substances that transfer sound are acoustical conductors. There are corresponding insulators for each type of conductor.
Very simply put, an ideal conductor is any material whose free electrons can move without any resistance. Of course, there are no perfect conductors, but many metals come amazingly close.
