Transferencia de calor

The video tutorial explains the three methods of heat transfer: conduction, convection, and radiation. Conduction involves the direct transfer of energy between molecules, primarily in solids. Convection occurs through the movement of fluids, where heated molecules move away from the heat source, creating convection currents. Radiation allows heat to travel through a vacuum, such as space, without the need for molecules, exemplified by the Sun's heat reaching Earth.
