Matter

Matter
Anything that has mass and takes up space (volume)

3 Physical States of Matter

• Solid
• Liquid
• Gas

3
Solid

• Particles are tightly compact
• Particles vibrate without the ability to move
  freely
• Definite shape and volume
• Solid Animation

4
Liquid

• Particles are tightly compact, but able to move
  around close to each other
• No definite shape, but definite volume
• Liquid Animation

5
Gas

• Particles can easily spread out or move close
  together
• Particle move freely and with a lot of energy
• No definite shape or volume
• Gas Simulation

6
Properties of Matter

• Physical Property
• Any property of matter that can be observed or
  measured without changing the identity of the
  matter
• Examples
• color
• shape
• taste
• density
• state/phase

D M V

Properties of Matter

• Chemical Property
• Any property of matter that describes a substance
  based on its ability to change into a new
  substance
• Examples
• flammability
• reactivity with vinegar
• reactivity with oxygen

Iron Oxygen ? Iron oxide (rust) 2Fe 3O2 ?
Fe2O3

Changes in Matter

• Physical Change
• a change in shape, size, color, or state
• a change without a change in chemical composition
• a change that is reversible
• The Mixtures Lab
• Examples
• tearing paper
• cutting your hair
• change in state

Chemical or Physical Property?

• Paper is white
• Boiling point of H2O is 100oC
• Zinc reacts with hydrochloric acid and creates
  hydrogen gas
• 4. Sulfur smells like rotten eggs

States of Matter Simulation

• Simulation 1
• Simulation 2
• This is what happens when energy is added and
  taken away

Changes in Matter

• Chemical Change
• a change in which a substance becomes another
  substance having different properties
• a change that is not reversible using ordinary
  physical means
• Changes that usually cause heat, sound, light,
  odor, fizzing/foaming, color changes
• You usually need more than one of the above
  characteristics to be considered a chemical
  change!
• Examples
• combining sulfuric acid and sugar
• burning a piece of wood
• soured milk

12
Chemical or Physical Change?

• Bending a Paper Clip
• Baking a cake
• You blow dry your wet hair
• Crushing an aluminum can
• Vinegar and baking soda combining to create salt
  and water
