Difference between conduction and radiation
Conduction |
Radiation |
When the transfer of heat takes place between the objects through the direct contact is called as conduction. |
Radiation involves the transfer of heat through the electromagnetic waves in which the particles are not involved. |
The rate of transfer of the heat is slow in the conduction system. |
The rate of transfer of heat in the radiation is fastest as compared to the convection and the conduction |
In the conduction the transfer of heat takes place because of the difference between the temperature of two system. |
Radiation takes place in the objects which have temperature more than 0 k. |
In the conduction the flow of heat is from the high temperature region to the low temperature region. |
It transfer the heat through all the bodies which follow the rule of temperature more than 0 k. |
In the conduction the transfer of heat takes place between the two solids. |
Radiation can takes place and transfer the heat through a large distance without intervening the medium. |
The heat transfer is takes place by direct and the physical contact. |
The transfer of the heat takes place in the radiation is due to the electromagnetic waves. |
In the solids the conduction takes place due to the collision of the molecules, the solid matter does not move actually. |
In the radiation the heat is not transferred through the actual flow of matter but due to electromagnetic waves without involvement of particles. |
Conduction does not obey the rule of reflection and refraction. |
Radiation obey the law of reflection and refraction. |
