Weather: Conduction, Convection, and Radiation

The video tutorial explains the three main methods of heat transfer: conduction, convection, and radiation. It begins with a practical example of a spoon in boiling water to illustrate conduction, where heat travels through direct contact. Convection is demonstrated with a wood fire heating a room, showing how heat moves through fluids. Finally, radiation is discussed, highlighting how energy from the Sun warms the Earth. Each method is explained with real-world examples to enhance understanding.
