Convection is heat transfer by mass motion of a fluid such as air or water. Convection does not occur in solids because the particles within are too tightly packed to facilitate the process. read more
CONVECTION. It is a heat transfer process in which heat tansfer occur due to the transfer of molecule from higher tempreature to lower tempreature. So, It is not possible within the solid. And as we know the molecules of solid are tightly bound to each other that they can possibly vibrate but there movement is not possible. 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
