1. Size Independent Physical Properties

2. The following do not depend on the amount of matter present:
Melting Point & Boiling Point
Density: the mass per unit volume of a substance.
Conductivity: ability to carry electricity
Solubility: ability of one substance to dissolve in another

3. Think Pair Share
If you change the amount of water in the pan, do you change the boiling point? Explain.
If I have a 3 cm block of copper or a 3 m block of copper, does the conductivity change? Explain.

4. Solving for Density
Density = Mass
Volume
mass

5. What is the density of an object with a mass of 16 grams and a volume of 25 mL?

6. What is the volume of a cup of water with a mass of 350 grams, if the density of water is 1 g/mL?

7. What is the mass of an object with a density of 2 g/mL and a volume of 358 mL?

8. What is the volume of a cup of water with a mass of 350 grams, if the density of water is 1 g/mL?

9. What is the density of an object with a mass of 450 grams and a volume of 150 mL?

10. What is the mass of an object with a density of 4 g/mL and a volume of 50 mL?

11. Think Pair Share
Explain how to use the density pyramid to solve density problems.
What has more mass, a pound of feathers or a pound of gold? Explain your reasoning.

12. Learning Scale
4 - Design an experiment to determine the identity of an unknown using its physical properties. 3 - Classify and compare substances based on their physical properties. 2 - Calculate and describe the densities of various materials through the measurement of their masses and volumes. 1 - Explain the difference between mass, weight, and volume.
