Exploring Thermal Energy Transfer Concepts

The video tutorial by Mr. Gardo covers the topic of thermal energy transfer, explaining how heat moves through conduction, convection, and radiation. It begins with an introduction to thermal energy as a form of kinetic energy, emphasizing its constant motion and presence in all substances. The tutorial then explores how heat moves from hot to cold until equilibrium is reached. Detailed explanations of the three methods of heat transfer—conduction, convection, and radiation—are provided, along with practical examples to illustrate each method. The video serves as a comprehensive guide to understanding thermal energy transfer.

What is thermal energy?

• The energy of light

• The total energy of all particles in a substance
