Explanation:
Conduction :
1} It is the transfer of heat by direct contact.
2) The reason for heat transfer is temperature difference.
Convention:
1) It involves the heat movement by actual motion of the matter.
2) This process takes place due to difference in densities.
Radiation
1) The rotation and vibration of atoms and molecules ensure that all substances continue to emit energy through electromagnetic radiation
2) Unlike conduction and convection which both require actual physical contact between two bodies, radiation is the heat transfer that occurs even when the bodies don’t come into contact or are separated in space.
