Learn about thermal conduction, convection, and radiation in this Khan Academy video.
There are three forms of thermal energy transfer: conduction, convection, and radiation. Conduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated.
Lesson 3: Modes of heat transfer. Thermal conduction, convection, and radiation. Thermal conduction. Thermal conductivity of metal and wood. Intuition behind formula for thermal conductivity. Thermal conduction (basic) Thermal conductivity - rods connected at a junction. Equivalent thermal conductivity.
Read this article to learn how to determine the rate at which heat conducts through a material.
