convection can occur in only in liquids and gases.
Convection is a phenomenon that exclusively affects liquids and gases. Convective heat transfer refers to the movement of heat from a fluid (gas or liquid) to a solid.
Convection is the mass motion of a fluid, like air or water, which transfers heat. Since the particles are closely packed to help with the process, convection does not happen in solids. Actual movement between particles is necessary for convection within a material.
Wherever there is movement of the medium's particles, convection occurs. This is only feasible in liquids and gases; it is not possible in solids.
