Heat Transfer Methods: Conduction, Convection, and Radiation Explained #3022315 (License: Personal Use)

This diagram visually explains thermal energy transfer: conduction occurs when a hand touches a hot metal rod; convection is shown by rising warm air above a fire; radiation is depicted as wavy lines emitted from the fire to nearby hands without direct contact. Each mode is labeled with arrows and real-world examples to clarify differences in mechanism and medium requirement.

Used in educational web pages, science textbooks, and STEM learning platforms to teach fundamental thermodynamics. Matches user intent for visual explanation of heat transfer concepts in middle school to undergraduate physics courses.
