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

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

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

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.
