Answer:
On a microscopic scale, conduction occurs as rapidly moving or vibrating atoms and molecules interact with neighboring particles, transferring some of their kinetic energy.
Conduction is the most significant form of heat transfer within a solid object or between solids in thermal contact.
Conduction is most significant in solids, and less though in liquids and gases, due to the space between molecules.
The rate of heat transfer by conduction is dependent on the temperature difference, the size of the area in contact, the thickness of the material, and the thermal properties of the material(s) in contact.
