1. Use the kinetic-molecular theory to explain what happens as anunknown solid is heated from below its freezing point to beyond itsboiling point.

2. You have two unknown substances, A and B. Each weighs 10.05g.When A is dropped into a beaker of water, it displaces 1.35mL of water. Similarly, when substance B is dropped into a different, butidentical beaker, it displaces 2.30 mL of water. Which substancehas the greater density?

3. An unknown liquid has a density of 0.79 g/cm3. How much does1.00 m3 of this substance weight?
