Transcription de la présentation

  1. Matter

  2. Matter • Anything that has mass (grams) and occupies space (volume). • Volume: a measure of the size of a body or region in three dimensional space. • Solid Volume (of a cube or rectangle): Length x width x height cm x cm x cm = cm3

  3. Matter • Liquid volume is found by using a graduated cylinder • Gas volume is the same as the container it fills.

  4. Matter • Mass – quantity of matter contained in an object. • Measured on a balance in grams, mg, etc. • WEIGHT is not mass! Weight is the gravitational force exerted on an object! It’s value can change from place to place. MASS is the same everywhere!

  5. Matter • Physical property: • A characteristic of a substance that does NOT involve a chemical change • Examples: • Density • Color • Hardness • Mass • Volume

  6. Matter Density • Mass and volume depend upon how much substance you have. The relationship between these two properties is called DENSITY. • Density can be used to help identify a substance.

  7. Matter Formula for density: Density = Mass = g or g Volume mL cm3 Also written as: D = m V

  8. Matter Density Problems 1. If mass = 129 g and volume = 10 mL, what is the density? 2. The manufacturer of a shampoo wants to determine how many grams of shampoo would fit in a 350 mL bottle. If the density of the shampoo was 19.8g/mL, how many grams of shampoo would fit in the bottle?

  9. Matter Classification: All matter is made of atoms. Atom: smallest unit of an element that maintains the properties of that element.

  10. Matter Two classifications: • Pure substances • Can be an element (gold) or a compound (water) • Has definite physical and chemical properties • Mixture • A combination of two substances that are NOT chemically combined (rocks and marbles)

  11. Matter Element – a pure substance that contain only one kind of atom • Silver • Copper

  12. Matter Compound • Composed of two or more atoms Example: Magnesium Chloride and Cobalt Chloride Cobalt Chloride 1 atom of Cobalt 2 atoms of Chlorine CoCl2 Magnesium Chloride 1 atom of Magnesium 2 atoms of Chlorine MgCl2

  13. Matter Mixtures • Contain two or more pure substances • Does not always have the same balance of ingredients • Example: air • Contains oxygen, nitrogen, etc.

  14. Matter Mixtures: two types • Homogeneous: pure substances are mixed evenly throughout 2. Heterogeneous: contains substances that are not evenly mixed Milk Iron and Sulfur

  15. Matter Distinguishing mixtures from compounds • Mixtures: • Two or more substances physically • mixed together • Substances may be present in • varying proportions • Properties of the mixture reflect the • properties of the substances it contains. Compounds: 1. Two or more elements chemically combined 2. Have a definite composition 3. Properties of a compound are different than the properties of the elements that make it up.
