• noun the ability of a material to conduct


  • The transmission of energy through a medium without the medium itself moving as a whole. Electrical, acoustic, or heat energy may be propagated in this manner. For instance, the transmission of electrical energy through a metal entailing the migration of electrons through the conductor. This contrasts with convection, where the medium itself is moved, and with radiation, where waves or particles are emitted.
  • The flow of electrical charge through a medium. This may entail, for instance the movement of electrons through a metal conductor, or the migration of ions in a gas. Also called electrical conduction.


  • noun the process of passing heat, sound or nervous impulses from one part of the body to another
