Why is convection not possible in solids?

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. read more

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

convection is not possible in solids because for convection to take place the molecules of a substance should be free to move like liquids and gases. The molecules of a solid are tightly packed together, thus making it difficult for molecules to move around for convection to take place. read more
