Heat Transfer: Radiation, Conduction, and Convection Explained Through Everyday Life

The video tutorial explains the three types of heat flow: radiation, conduction, and convection. Radiation is described as the transfer of heat through a vacuum, exemplified by the sun's heat reaching Earth. Conduction is illustrated by the transfer of heat from hot metal handlebars to cooler hands. Convection is demonstrated through boiling water, where hot water rises and cold water sinks, forming convection currents. The video concludes by summarizing these heat flow methods and introducing the concept of thermal equilibrium, where objects reach the same temperature.
