3
Physical Property Characteristic observed of material without changing substances. EXAMPLES: color, brittleness, boiling and melting points, reflectivity, shape, magnetic attraction, state of matter and density
4
Physical Property Some physical properties can be measured. What physical properties of this water can be measured?
5

6
Physical Changes What happens if you break a piece of chalk? Does it change the identity of the material?
7
Physical Change Does not change identity of substances in material. EXAMPLES: Changes of state, shape. Separation of substances in mixture, e.g. by evaporation, magnetism, filtering.
8
Chemical Change A substance changes into another substance or substances. SIGNS: Change of odor, production of gas, release of light or heat energy.
9
Chemical Change EXAMPLES: Iron rusting, fireworks exploding, burning
10
Chemical Change Chemical reactions are chemical changes. 2H 2 + O 2 --> 2H 2 O
11
Chemical Properties Characteristic of a substance that indicates whether it can undergo a specific chemical change. EXAMPLES: pH, flammability, reactivity with water. Acid is low pH, less than 7. Base is high pH, greater than 7.
