Heat Transfer Concepts

The video tutorial introduces the concept of heat transfer, explaining it as the movement of energy from one object to another. It covers the three forms of heat transfer: conduction, convection, and radiation, providing examples for each. Conduction involves direct contact, convection involves fluid movement, and radiation involves energy transfer through space. The video concludes with interactive questions to reinforce learning.
