heat is just the transfer of energy from a point of high temperature to a point of lower temperature ex. if a sidewalk is hotter than your foot and you step on it, some of the heat from the sidewalk...

Heat is not a molecule, it's a form of energy. It is conducted from molecule to molecule in conduction and convection (not in heating by radiation). Molecules with high kinetic energy give their...

the molecules do nothing and the heat does nothing;)Actually,the molecules spread apart because of the heat!!!!
