Conductors.
electricity
True of False? Heat is the motion of atoms and particles.
False. It Heat is the motion of ATOMS and MOLECULES.
______ energy is related to the motion of tiny particles in matter. The faster the particles move, the warmer a substance gets and more energy it has.
Thermal

A _______ reaction can produce heat, examples are when you make a fire or melt ice.
Chemical
True of False? Molecules move faster in cold liquids than in hot.
False. Heat causes particles to move faster and spread out.
