WebAboutTranscript. There are three forms of thermal energy transfer: conduction, convection, and radiation. Conduction involves molecules transferring kinetic energy to one another through collisions. Convection occurs when hot air rises, allowing cooler air to come in and be heated. Thermal radiation happens when accelerated charged particles ... WebConduction Conduction is a process by which heat is transferred from the hot area of a solid object to the cool area of a solid object by the collisions of particles. In other words, in solids the atoms or molecules do not have the freedom to move, as liquids or gases do, so the energy is stored in the vibration of atoms.
