Heat types refer to the different ways heat energy can be transferred. The three main types are conduction, convection, and radiation. Conduction occurs when heat moves through a solid material, like a metal spoon in a hot pot. Convection involves the movement of heat through fluids, such as water or air, where warmer areas rise and cooler areas sink. Radiation is the transfer of heat through electromagnetic waves, which can occur in a vacuum, like the warmth from the sun reaching the Earth. Each type plays a crucial role in everyday processes, from cooking to weather patterns.
