Does convection occur in solids?

Convection does not occur in solids because the particles within are too tightly packed to facilitate the process. Convection requires actual movement between the particles within a substance in order to transfer heat which is only possible in a fluid state of matter such as liquid or gas. read more

Convection is a nonessential heat transfer mechanism in solids because solids do not transport thermal energy via collective, bulk motions of constituent particles across macroscopic length scales. Convection is a bulk flow of material---the collective, macroscopic motion of uncountably many particles, e.g., a gust of wind or the flow of lava. read more

the particles in a solid are tightly bonded together and are not free to move so convection cannot occur. a solid must be heated to a liquid before the particles can move freely . read more
