Difference Between Conduction, Convection and Radiation
Transfer of heat takes place via conduction, convection and radiation. Difference between them is listed in the table given below:
|
Parameter |
Conduction |
Convection |
Radiation |
|---|---|---|---|

Medium |
Medium is required. |
Medium is required. |
Medium is not required, can occur in vacuum. |
|
Method of Heat Transfer |
Transfer of heat takes place by direct physical contact. |
Transfer of heat takes place my motion of particles. |
Transfer of heat takes place by electromagnetic radiation. |
|
Reason |
Occurs due to difference in temperature between two substances. |
Occurs due to difference in density between two substances. |
Occurs at all bodies which have temperature above absolute zero (0K). |
|
Process |
It is slow process. |
It is a faster process than conduction. |
It is fastest process of all three modes. |
|
Path of Heat Transfer |
Path of transfer of heat is irregular. |
Path of transfer of heat is irregular. |
Path of transfer of heat is linear. |

Conduction
Conduction is the transfer of energy (heat or electricity) from one object to another when there is direct contact between these objects. During Conduction, a molecule gains energy and starts vibrating. This energy is then transferred to the other surrounding molecules until complete transfer of energy within the body is complete.
In this article, we will understand the meaning of conduction, types of conduction, Fourier’s Law, Conduction Resistance, and Heat conduction along with the difference between conduction, convection, and radiation.
