Matter Properties

• Chapter 3

2
Matter

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

3
Substances

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

4
Formulas Identity

• Element 1 upper case letter
• Compound 2 or more upper case letters

5
Properties of Matter

• Section 3.1

6
Physical Properties

• Describe the appearance and behavior of matter

-Words color, texture, luster, odor, solid,
liquid, gas. -Measurements a number and a unit.
Qualitative
Quantitative

Intensive properties

• are independent of the sample size.
• Physical Constants are quantitative intensive
  properties. They have a number and a unit.
• 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
Properties of Copper

• 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.

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.)

States of Matter
source

1. How are the particles packed in each phase?
2. How do the particles move in each phase?
3. Why do liquids and gases flow?
4. Why are gases so easy to compress?

14
4th Phase of matter

• Plasma exists in stars, lightning
• Electrons are stripped from atoms.

15
Phases of Matter

• Solid
• Liquid
• Gas
• TIGER

16
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)
