### Classification of Matter

1. 1. Ch 16: Properties of Matter Mrs. Neistadt Physical Science
2. 2. Notes Chapter 16.1*What is Matter?*Matter is a term used to describe anything that has mass and takes up space.
3. 3. Classifying Matter• *Matter is divided into two categories: mixtures and substances.• *Mixtures contain more than one kind of matter. – For example: Cola is a mixture of carbonated water, corn syrup, caramel color, phosphoric acid, natural flavors and caffeine.
4. 4. Two Types of Mixtures• *A Homogeneous Mixture is the same throughout. – Examples: unopened cola, gasoline, peanut butter• *A Heterogeneous Mixture has differences throughout a sample. – Examples: chicken noodle soup, salad, rocky road ice cream
5. 5. What is a Substance• *A Substance cannot be separated into different kinds of matter by physical methods. (sorting, filtering, heating, cooling) – Example: table salt (sodium + chlorine) – *A substance that contains only ONE type of matter is called an Element. • Sodium is an element, as is chlorine
6. 6. Periodic Table of Elements
7. 7. What is a compound?• * A Compound is a substance made of two or more elements that cannot be separated by physical means. (sorting, heating, cooling, filtering)• Is saltwater a compound?
8. 8. 16.1 Classifying MatterKey Question:How can a homogenous mixture be separated?
9. 9. Notes Chapter 16.2 Measuring MatterDaily Question: How do we measure matter?1. If its liquid: find its volume2. If its solid: find its mass3. If its irregular: use the displacement method
10. 10. • To find the volume, simply measure in a marked container.• To find mass, use a balance.
11. 11. What if the item is an odd shape?• The Displacement Method works to find the mass of irregularly shaped objects.
12. 12. What is the volume of the objects?
13. 13. How can we determine the amount of matter in a rock?1. Measuring the mass of the rock on a balance2. Measuring the volume of the rock by using displacement technique
14. 14. Notes Chapter 16.3DQ: What are the four states of matter? (hint: pg 292)SolidLiquidGasPlasma
15. 15. Molecules and Atoms• *A Molecule is the smallest part of a compound that retains its properties.• *An Atom is the smallest part of an element.• Atoms are more than a trillion times smaller than what we can see with a microscope.
16. 16. Atoms are always moving• *At higher temperatures there is more energy- so atoms move faster• *At lower temperatures there is less energy- so atoms move slower• *Temperature influences the changes of state of an atom or molecule.
17. 17. States of Matter• *Solid- retains its shape and size; Molecules vibrate, but cannot change position.
18. 18. States of Matter• *Liquids- has a definite volume, but no definite shape; molecules can move over and around each other and will fit into whatever container its poured into.
19. 19. States of Matter• *Gas- has no definite size or shape; molecules float around freely and will spread out evenly throughout the container
20. 20. States of Matter• *Plasma- atoms heated to such high temperature they lose their outer layer of electrons. Not often found on Earth, but makes up 99% of matter in the universe.
