  1. What’s aMATTER? Chapter 2 Pre-requisite

  2. A. Definiton: Anything that has mass and takes up space! B. The Law of Conservation of Matter: by Antoine LaVoisier • Matter is neither created nor destroyed yet • converted from one form to the next.

  3. C. The states of Matter? • Solid • Liquid • Gas • Plasma Video

  4. D. One Factor that can affect the state of matter is: Temperature If I increase it, how will the state change? The molecules Kinetic Energy increases. Kinetic Energy = Energy in motion

  5. VI. Temperature Scales • C= F-32 • 1.8 Freezing water: 0oC Boiling water: 100oC 1. Celsius: Andres Celsius (1701-1744) 2. Fahrenheit: Gabriel Fahrenheit; (1686-1736) Freezing water: 32oF Boiling water: 212oF F=C X1.8+32 3. Kelvin: The International system of Units (SI); William Thomson Lord Kelvin (1824-1907) K= oC + 273

  6. Examples: K = oC + 273 oC = K - 273 37 C= 310-273 • 310K=___________C • 25C=____________K • 37C=____________K • -62C=___________K • 50K=___________C • 163C=___________K • 75F=____________K 298 K= 25 + 273 310 211 -223 C= F- 32 1.8 436 C= 75- 32 1.8 = 24 oC 297 K= 24+ 273

  7. So….What’s the lowest possible temperature reached? Write this down ABSOLUTE ZERO: 0K is = -273oC. The point at which the motion of particles of matter ceases (STOPS)!! NO NEGATIVE K’s

  8. STOP here!!

  9. Changes in Matter can be physical or chemical A. Physical change: Identity of substance is NOT altered. B. Chemical change: New substance has different set of properties. Changes in Matter Video clip

  10. C. Forms of Matter a. Element: Smallest, indivisible part of a substance When a metal and nonmetal combine by giving and taking electrons! Ex: Table salt b. Compound: When two or more nonmetals combine by sharing electrons!! Ex: Water (H2O) c. Molecule:

  11. d. Mixture: i. Homogeneous Mixture: Visible components are all similar

  12. d. Continuation w/Mixtues ii . Heterogeneous Mixture: Has visible distinction between parts

  13. Yeah! Done with the pre-requisite stuff!
