Because convection occurs by convection currents. Convection currents occur as a result of the movement of a body. Since solids cant move, convection only occurs in fluid, i.e., liquids and gases
Convection entails the bulk movement of fluids at one temperature into a region where the surrounding fluid is at a different temperature. Convection is easier in a gas than a liquid because gases are much less viscous than liquids so there is less resistance to the movement of the gas.
In a solid, atoms and molecule are fixed in place and the material of a solid does not flow, so there can be no convection.
because solids have stiff bonds and cannot move freely.
It does occur in gases but not solids, because the molecules in a solid are not free to move and transfer heat by moving.
Because solids don't flow much.
Yes !
Convection
Because they both flow easily.
usually gases, but sometimes liquids
That's called "convection".
transfer heat by fluid motion

heat energy
In liquids by convection and by radiation in gases
Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.
