Uncountable noun

Definition

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.

Examples

“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.”

Examples

simple

contextual

“Good thermal conduction is essential for the efficient operation of a central heating system.”

complex

“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.”

Real-World Examples

“SWANS relies on ionic conduction just like neurons, which communicate by shuttling sodium and potassium ions through their membranes, creating voltage differences.”
Ars Technica 30 Sept 2026
“The material displayed a flat electronic band, meaning that the range of electron energies associated with electrical conduction changed very little.”
ScienceDaily 2 Oct 2026
“Heat comes from a combination of conduction (contact with the hot drum surface) and convection (hot air moving through the drum).”
Green Coffee Collective 16 Apr 2026
“In conventional materials, heat spread outward in circular patterns, which is consistent with normal diffusive heat conduction.”
