1. Chemical and Physical Properties

2. Physical Properties Physical properties can be determined without changing the identity of the substance. Examples???

3. Viscosity Resistance to flowing Maple Syrup- High Viscosity Water- Low Viscosity

4. Ductility Ability to be drawn into a thin wire

5. Malleability Ability to be hammered into thin sheets without shattering

6. Hardness A substance’s resistance to being scratched

7. Solubility Ability to dissolve in water –Yes! It is a physical property because you do not need to alter identity of the substance to determine solubility.

8. Conductivity Ability to carry electricity Superconductor? Semiconductor?

9. Other examples of physical properties….

10. Chemical Properties Describe the way a substance can change or react to form other substances. Must be determined using a process that changes the identity of the substance
