Heat transfer is the movement of thermal energy from one object to another. There are three modes of heat transfer: conduction, convection, and radiation.

• Conduction is the transfer of heat through a material without any movement of the material itself. Example: Touching a hot stove.

• Convection is the transfer of heat through the movement of fluids (liquids or gases). Example: Boiling water.

• Radiation is the transfer of h...read more
