Explaion conduction, convection and radiation with examples.

Explanation

Conduction : In is a mode of transfer of heat from one part of the body to another , from particle to particle in the direction of fall of temperature without any actual movement of the heated particles.
Ex: When one end of a metal rod is heated its other end becomes hot . Here, the heat goes from hot end of the metal rod towards cold end by conduction .
Convection : It is a mode of transfer of heat from one part of the medium to another part by the actual movement of the heated particles of the medium .
Ex: Seabreeze, Tradewind , etc .
Radiation : It is a mode of transfer of heat from the source to the receiver without any actual movement of siurce or receiver and also without heating the intervening medium.
Ex: Heat from sun comes to us through radiation . On standing near fire, we feel hot as heat comes to us though radiation .
