Convection:

Convection

Mode of transfer of heat by means of migration of material particles of medium is called convection. It is of two types:

(1)  Natural convection : Theis arises due to difference of densities at two places and is a  consequence of gravity.

(2)  Forced convection: If a fluid is forced to move to take up heat from a hot body then the convection process is called forced convection
