conduction
This term describes a seamless, direct transfer of energy through a medium without the medium itself moving. It evokes the image of a domino effect at a microscopic level, where particles vibrate or electrons shift to pass energy to their immediate neighbors. This distinguishes it from convection, where the material actually flows, or radiation, which travels through a vacuum.
In professional and scientific discourse, the word carries a neutral, clinical tone. It is used almost exclusively in physics, engineering, and biology to describe the mechanics of energy transport, such as the way nerves transmit electrical impulses throughout the human body.
Used as a scientific phenomenon or process, such as discussing the thermal conduction of a metal.
Meanings
The process by which heat or electricity is directly transmitted through a material when a difference in temperature or electrical potential exists.
The conduction of heat through a copper rod is very efficient.
