Full Answer

Convection, one of the major types of heat transfer, involves energy moving from high areas of heat to low areas. If one area is hotter than a nearby area, heat will be transferred until both areas are the same temperature. Conduction occurs between two substances in contact. Energy is transferred as a result of molecular movement and interaction. Radiation heat transfers occurs on some level from all objects, as atoms emit energy as electromagnetic waves, which can be absorbed by other atoms.
