2 The following do not depend on the amount of matter present: Melting Point & Boiling PointDensity: the mass per unit volume of a substance.Conductivity: ability to carry electricitySolubility: ability of one substance to dissolve in another
3 Think Pair ShareIf 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.

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 ShareExplain 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 Scale4 - 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.
