1. Physical Properties of Matter
Color
Odor
Mass
Volume
Density
Thermal Conductivity
State
Malleability
Ductility
Solubility
Physical Property:
A physical property of matter can be observed without changing the identity of the matter.

2. Chemical Properties of Matter
Flammability
Non flammability
Reactivity (general)
Specific:
with oxygen
with bleach
with acid
Chemical Property:
A chemical property can be observed only when one substance might become a new substance

3. What is the difference between a physical and chemical change?
When a substance undergoes a physical change, its identity remains the same. Ex: Ice melting Cutting your hair Bending wire Cutting wood (physical changes can often be undone.)
When a substance undergoes a chemical change new substances with different properties are formed. Ex: Steel reacts with oxygen to form rust Baking a cake Milk souring (chemical changes cannot be undone without further chemical changes)

4. Evidence of Chemical Change
Color Change
Bubbles
Heat
Odor
Light
Precipitate

5. Examples of Chemical Changes

6. Sulfuric acid and sugar
Heating sugar

7. Exothermic vs. Endothermic
Gives off Heat
Takes in energy/becomes cold

8. Forms a PRECIPITATE

9. A = 0.5 M copper (II) sulfate B = 0.5 M sodium thiosulfate
