Conduction

Conduction

Definition: The process of thermal energy transfer without any flow of the material medium.
Without any flow of the material medium=Without the medium moving
Heat is transmitted through a medium from its hotter part to its colder part until they are both at the same temperature.
Conduction happens in all matter as long as there is a medium.
The 3 main medium are solids, liquids and gases. Transfer of heat energy is fastest in solids, and slowest in gases.
