10. Describe the physical properties (their volume and shape) of the states of matter: Solid: definite shape, definite volume Liquid: definite volume, not a definite shape - Liquids will take the shape of their container Gas: not a definite shape or volume - Gases change shape and volume to fill any container

11. A) 8 ounces of water will boil at 100°C. At what temperature will 1,800 ounces of water boil at? 100°C B) Why? Water will always boil at 100°C, regardless of the amount of water.

12. What happens to the amount of mass in an object when it goes from a solid to a liquid or from a liquid to a gas? The amount of mass does not change. (Matter is neither created or destroyed.) 13. Name some physical properties used to describe a rock. Any property that can be observed without changing the identity of the substance: Density, odor, hardness, color, shine, shape, texture

14. A) What is a physical change? Changing something without changing the substance B) Give an example of a physical change. Melting, Boiling, Freezing
