Heat Transfer: Exploring Conduction Convection and Radiation

The video tutorial explains heat transfer, which is the movement of energy between objects of different temperatures. It covers three main methods of heat transfer: conduction, convection, and radiation. Conduction involves direct contact between objects, convection involves the movement of fluids, and radiation occurs without physical contact. Examples such as boiling water, cooking on a skillet, and lava lamps are used to illustrate these concepts. The video concludes with a suggestion to explore more about these topics through a playlist.

What is heat transfer primarily described as?
