INTRODUCTION:

In heat transfer, it can also be transferred by conduction. Have you ever

noticed that a simple bar heated by candle becomes warmer because the fire from

the candle is conducted along the simple bar?

Heat conduction is the flow of internal energy from a region of higher

temperature to one of lower temperature by the interaction of the adjacent particles

in the intervening space. Conduction is most effective in solids but it can happen in

fluids and gas. In solids, it is due to the combination of vibrations of the molecules in

a lattice and the energy transport by free electrons. The flow of heat by conduction

occurs via collisions between atoms and molecules in the substance and the

subsequent transfer of kinetic energy.  It is the transfer of energy through matter

from particle to particle. It always takes place from a region of higher temperature to

a region of lower temperature. In gases and liquids, conduction is due to the

collisions and diffusion of the molecules during their random motion. For another

example the heat conduction is a spoon in a cup of hot soup becomes warmer

because the heat from the soup is conducted along the spoon.
