1 Unit 6, Chapter 16 Integrated Science

2 Unit Six: Properties of Matter 16.1 Classifying Matter 16.2 Measuring Matter 16.3 States of Matter Chapter 16 What is Matter?

3 Chapter 16 Learning Goals Classify samples of matter from everyday life as heterogeneous mixtures, homogeneous mixtures, compounds, or elements. Measure volume using the displacement technique. Measure mass with scales and balances. Use an indirect technique to infer mass from density measurements. Identify the states of matter. Classify the states of matter in order of energy. Recognize changes in state as a physical change in matter. Explain the states of matter in terms of molecular motion. Identify and investigate the law of conservation of mass.

4 Chapter 16 Vocabulary Terms atom compounds elements heterogeneous mixture homogeneous mixture law of conservation of mass matter mixtures molecule substances

5 16.1 Classifying Matter Mixtures contain more than one kind of matter. — A homogeneous mixture is the same throughout.

6 16.1 Classifying Matter — Two samples of a heterogeneous mixture could be different.

7 16.1 Classifying Matter Mixtures can be separated be physical means such as: — sorting — filtering — heating — cooling

8 MIXTURES MATTER SUBSTANCES Heterogeneous mixtures Homogeneous mixtures ElementsCompounds

12 16.2 Measuring Matter Measuring volume — Read volume marks at eye level for accuracy.

13 16.2 Measuring Matter Measuring volume — You can calculate volume of solids using formulas.

14 16.2 Measuring Matter Key Question: How is matter measured? *Read text section 16.2 BEFORE Investigation 16.2

15 16.3 States of Matter Scientists call the smallest possible particle of a compound that retains the properties of the compound a molecule. The smallest possible particle of an element is called an atom.

17 16.3 States of Matter Changes of state at 1 atm. of pressure (normal pressure at sea level)

18 16.3 States of Matter All substances can exist as a solid, liquid, or gas. Solids: — A solid retains its size and shape.

19 16.3 States of Matter Liquids: — A liquid has a definite volume, but no definite shape. — Liquids flow to take the shape of the container.

20 16.3 States of Matter Gases: — A gas has no definite shape or size. — Gases expand to fill their containers.

21 16.3 Four States of Matter Plasma is found in the core of our sun and stars.

22 16.3 States of Matter Key Question: How fast can you melt an ice cube? *Read text section 16.3 BEFORE Investigation 16.3

23 16.3 Investigation Results
