Chapter 16 What is Matter?
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.

16.1 Classifying Matter
Mixtures contain more than one kind of matter.
— A homogeneous mixture is the same throughout.
16.1 Classifying Matter
Mixtures can be separated be physical means such as:
— sorting
— filtering
— heating
— cooling
16.1 Classifying Matter
Key Question:
How can a homogenous mixture be separated?

16.2 Measuring Matter
Key Question:
How is matter measured?

16.3 States of MatterScientists 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.
16.3 States of Matter
All substances can exist as a solid, liquid, or gas.
Solids:— A solid retains its size and shape.
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.
16.3 States of Matter
Gases:— A gas has no definite shape or size.— Gases expand to fill their containers.
16.3 States of Matter
Key Question:
