MODES OF HEAT TRANSFER

There are three ways to transport energy from one location to the other

1) Conduction
2) Convection
3) Radiation

CONDUCTION

In the case of conduction the particles share energy with neighbours. In this case the

energy of the thermal motion is passed along from one molecule to the next , while each

individual remains at its original position. Apart from the atomic vibrations , the rate of

conduction also depends on the properties of the substance. For example , it is possible to

hold a piece of asbestos in a flame indefinitely. This implies that very ...
