What is Heat Transfer? Heat is transferred from one object to another in three possible ways, Conduction, Convection and Radiation. Conduction occurs when heat energy is passed through a material from one particle to the next. The particles at the warm end move faster and hit the particles next to them causing them to move faster, in this [...]
