Changes in Matter
Physical Change
Dissolving
Bending
Breaking
Cutting
Change of State
Composition of matter is the same
Endothermic Reaction
Absorbs Energy
Reactants + Energy = Product
Photosynthesis
Evaporation
Exothermic Reaction
Products + Energy = Reactants
Combustion Reactions
Fires
Releases Energy
Opposite of Endothermic
Chemical Change
Bubbles, color change, odor, loud sounds
Usually can't be undone
Composition of matter changes
Different material than the one we start with
Liquid to solid = Precipitate
