The process by which heat or electricity directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
- the process by which sound waves travel through a medium.
- the transmission of impulses along nerves.
Conduction in science is when energy moves from one place to another place by touch. electricity conductors and heat conductions are the two most important kinds. In heat conduction, the heat energy travels from the hot point to a cold point. Something that energy can easily move through is a good conductor. metal is a good conductor. An insulator a poor conductor. An example is rubber. Energy cannot move quickly through an insulator. plastics are insulators. Some materials, such as glass, are conductors for heat but not electricity.
