What is heat transfer by convection possible only in liquids and gases?

Answer 1

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

Answer 2

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.

Answer 3

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.

Answer 4

because solids have stiff bonds and cannot move freely.

Answer 5

It does occur in gases but not solids, because the molecules in a solid are not free to move and transfer heat by moving.

Answer 6

Because solids don't flow much.

Answer 7

Yes !
