1. Changes in Matter

2. Properties We can classify matter by the properties that it has
We separate properties into two categories: physical and chemical

3. Physical Properties
Anything that can be measured or observed without forming a new substance is a physical property
These can be quantitative (has a number value) or qualitative (has a quality)

4. Chemical Properties
Anything that describes how a substance reacts with another substance to form something new is a chemical property

6. Physical Changes
A substance changes in form, but not in chemical composition
Physical changes can be reversed
Ex. Ice melting, chlorine being dissolved in water

7. Chemical Changes
A chemical change will cause one or more new substances to be formed
A chemical change can not be reversed
Ex. Cooking food, mixing baking soda and vinegar

8. Indicators of a Chemical Change
Change in temperature
Change in colour
Change in odor
Formation of a precipitate (solid)
Formation of bubbles (gas)
