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
— Two samples of a heterogeneous mixture could be different.
16.1 Classifying Matter
Mixtures can be separated be physical means such as:
— sorting
— filtering
— heating
— cooling

16.2 Measuring Matter
Measuring volume— Read volume
marks at eye level for accuracy.
16.2 Measuring Matter
Measuring volume— You can calculate volume of solids using formulas.
16.2 Measuring Matter
Key Question:
How is matter measured?
*Read text section 16.2 BEFORE Investigation 16.2
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
Changes of state at 1 atm. of pressure (normal pressure at sea level)
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 Four States of Matter
Plasma is found in the core of our sun and stars.
16.3 States of Matter
Key Question:
How fast can you melt an ice cube?
