1 Physical and Chemical Properties and Changes

2 Physical Properties: The characteristics of a substance that can be observed without changing the identity of the substance.

3 Chemical Properties: Chemical properties describe how substances can form new substances.

4 Physical Change: Physical change is a change that in the physical properties of a substance but, does not change the identity of the substance.

5 Physical Changes Clues of Physical Changes: A change in shape.
A change in size. A change in the state or phase of matter. Dissolving Sometimes a color change. Melting, freezing, boiling, evaporation, condensation, and sublimation.

6 Scientific Terms Malleability Ductility Luster Solubility Viscosity
Buoyancy Density Mass Volume

7 Examples of Physical Changes:
Ice melting A pencil sharpened Water boiling The formation of dew Dissolving Kool-Aid A candle melting

8 Examples of Physical Changes:

9 Chemical Change: Chemical change is the change of one substance into another substance.

10 Chemical Changes Clues of Chemical Changes: Foaming, fizzing.
A change in odor. Rapid production of heat, light, or sound. Color change. Formation of precipitate. New substance formed.

11 Scientific Terms Flammability Combustibility Oxidation Reactivity

12 Examples of Chemical Changes:
