Exploring Thermal Energy: Radiation, Convection, and Conduction

This video tutorial introduces thermal energy, also known as heat energy, explaining its definition and how it is produced. It discusses the role of thermal energy in everyday life, such as cooking and heating, and explains how it is transferred through convection, conduction, and radiation. The video also covers the characteristics of thermal energy and concludes with a call to action for further learning.
