Conduction
Conduction is the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material as a whole.
Conduction of Heat
In the context of heat transfer, conduction occurs when there is a temperature difference between two parts of a solid, or between a solid and a fluid, and heat is transferred through the collision of particles. The particles with higher kinetic energy collide with particles of lower kinetic energy, transferring energy and increasing the overall temperature of the material.
Conduction of Electricity
In the context of electricity, conduction refers to the flow of electric charge carriers through a conductor. In conductors, such as metals, the outer electrons of the atoms are loosely bound and are free to move through the material, allowing for the transfer of electric charge.
