2 When a substance changes from one state of matter to another, the composition of the substance remains the same. The original substance still exists, it has only changed form.

10/16/20153 Freezing Melting of ice cream Hardening of melted wax Evaporating of water from wet clothes Boiling Dissolving sugar or salt in water Stretching a rubber band Wadding up a piece of paper Denting a piece of metal Shredding paper

10/16/20154 Result in the formation of one or more new substances with new chemical and physical properties. SOMETHING NEW IS PRODUCED!!!!!!

10/16/20155 COLOR CHANGE Iron rusts bleach added to clothes brown apples black marshmallows. TEMPERATURE CHANGE Wood burns to ash and the temperature increases. FORMATION OF A PRECIPITATE Two solutions are combined to form a solid substance. FORMATION OF A GAS Gas bubbles Vinegar added to baking soda creates foaming. Water is heated to boiling.
