Answer 1

1. Convection is the transfer of heat energy through the movement of fluid particles. Hence, convection cannot take place in solids, since the solid particles are not fluid. Thus, convection only takes place in liquids and gases.

2. Conduction Heat Transfer. ... Conduction heat transfer in gases and liquids is due to the collisions and diffusion of the molecules during their random motion. On the other hand, heat transfer in solids is due to the combination of lattice vibrations of the molecules and the energy transport by free electrons.
