HEAT ENERGY AT WORK ave you ever sat near a campfire Could you feel its heat Touch your forehead People give off heat too Heat is a type of energy Every substance contains this type of energy The more heat energy something has the higher its temperature SNOW HAS LITTLE HEAT ENERGY FIRE HAS A LOT OF HEAT ENERGY
ATOMS MOLECULES Heat is created by the movement of atoms Atoms are very small Everything is made of atoms Atoms can bond together Bonded atoms form molecules Hydrogen and oxygen atoms bond to form water Atoms and molecules are always moving They move faster when heat energy is added The temperature of the substance rises Removing heat energy slows the atoms and molecules down The temperature of the substance lowers WATER MOLECULE OXYGEN ATOM HYDROGEN ATOMS
