conduction
n.the process of heat or electricity moving through a material. It happens when the particles in the material pass the energy to each other.
n.the transfer of heat or electricity through a substance by the movement of its particles. In physics, it refers to the process by which energy is transmitted through a medium without the medium itself moving.
“The metal pot conducts heat very quickly.”
“Good thermal conduction is essential for the efficient operation of a central heating system.”
“While conduction is the primary method of heat transfer in solids, it is significantly less effective in gases due to the vast distances between individual molecules.”
“In conventional materials, heat spread outward in circular patterns, which is consistent with normal diffusive heat conduction.”
Borrowed from Latin conductio, conductionem (“a bringing together”); equivalent to conduct + -ion.
