Gas Before ____ grams After ____ grams Prediction: A physical change is a change in size, shape, color or state of matter. A chemical change is when a new substance is made by rearranging the atoms. Its properties are different from the original materials. Everything from before weighed the same as everything after. This is the Law Of Conservation Of Mass. Notes: 6. (mix, re-weigh)

Conservation of Matter. Chemical Reactions Happen all of the time Happen naturally or can be man made Can be physical or chemical PHYSICAL CHEMICAL.
Heat and Temperature All particles are always in motion, even in solids. Kinetic energy= The energy of motion. Heat= a measure of the total kinetic energy.
