Definition of Conduction. the result of collisions between molecules; when one end of an object is heated, the molecules vibrate faster and the energy is transferred to their neighbors. Definition for Conduction :1. Thermal conduction the transfer of heat between two solid materials that are physically touching each other.2.
When conduction takes place, it is always a matter of heat moving from the hotter object to the colder, meaning when two objects are in contact with each other-one that is hot and one that is cold-the heat will always transfer to make the other object hotter, not the other way around.Examples of Conduction: 1.his is an example of conduction as the heat generated in the engine fills the compartment that houses it; the metal components that hold the engine in place have also heated up due to direct contact with the heat source.
