Transcript

  • 1. Ch 16: Properties of Matter Mrs. Neistadt Physical Science
  • 2. Notes Chapter 16.1*What is Matter?*Matter is a term used to describe anything that has mass and takes up space.
  • 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. 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. 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. Periodic Table of Elements
  • 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. 16.1 Classifying MatterKey Question:How can a homogenous mixture be separated?
  • 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. • To find the volume, simply measure in a marked container.• To find mass, use a balance.
  • 11. What if the item is an odd shape?• The Displacement Method works to find the mass of irregularly shaped objects.
  • 12. What is the volume of the objects?
  • 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. Notes Chapter 16.3DQ: What are the four states of matter? (hint: pg 292)SolidLiquidGasPlasma
  • 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. 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. States of Matter• *Solid- retains its shape and size; Molecules vibrate, but cannot change position.
  • 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. States of Matter• *Gas- has no definite size or shape; molecules float around freely and will spread out evenly throughout the container
  • 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.
