  1. Matter Properties

  2. Matter • Anything that has mass and occupies space. • Mass is measured in grams or kilograms. • Space or volume is measured in liters or cm3.

  3. Definition of Matter • First must recognize common properties. • Inertia – resistance to change in motion • Weight vs. Mass • Weight is a measure of the earth’s gravitational attraction for matter (force). • Mass is a measure of the quantity of matter. Law of Conservation of Matter

  4. Substances • Matter that has the same composition all the way through. • Pure • Elements or Compounds • H2O, NaCl, O2, He

  5. Formulas = Identity • Element = 1 upper case letter • Compound = 2 or more upper case letters

  6. Physical Properties • Describe the appearance and form of matter • -Words: color, texture, luster, odor, solid, liquid, gas. • -Measurements:a number and a unit. Qualitative Quantitative

  7. Physical Properties • Use them to identify matter! Memory Jogger

  8. Intensive properties • Physical Constants are independent of the sample size. • Density, freezing point, and melting point • Solubility in water (g/ml) • Heat of fusion, Heat of vaporization, Specific heat capacity

  9. Extensive Properties • Extensive properties depend on the amount of matter in the sample. • Mass & Volume

  10. Chemical Properties • Describe how matter behaves (changes) in the presence of other matter. • Flammability • Resistance to corrosion • Ability to neutralize acids or bases

  11. Physical Prop. Reddish brown Shiny Malleable Ductile Good Conductor Density = 8.92 g/cm3 MP = 1085C BP = 2570C Chemical Prop. Reacts to form green copper carbonate Forms a deep blue solution when in contact with NH3 Forms new substances with HNO3. Properties of Copper

  12. Phases • Solid – Definite volume and definite shape. • Liquid – Definite volume and indefinite shape. • Takes the shape of its container. • Gas – Indefinite volume and indefinite shape. • Takes the shape and volume of its container.

  13. States of Matter source • How are the particles packed in each phase? • How do the particles move in each phase? • Why do liquids and gases flow? • Why are gases so easy to compress?

  14. 4th Phase of matter • Plasma – exists in stars, lightning • Electrons are stripped from atoms.

  15. Notation of Phase • After the formula, use the letters: • s for solid • g for gas • l for liquid • aq means dissolved in water Al(s) H2O(g) CH3OH(l) • NaCl(aq) The state or phase of matter is a physical property!
