Heat Transfer: Conduction, Convection, and Radiation

Heat Transfer: Conduction, Convection, and Radiation Introduction We have learned that heat is the energy that makes molecules move. Molecules with more heat energy move faster, and molecules with less heat energy move slower. We also learned that as molecules heat up and move faster, they spread apart and objects expand (get bigger). This is ...
