Matter

Is what forms the things we can touch
1. General properties
  1. Mass
    1. The amount of matter.
    2. Measure: Kilogrames
  2. Volume
    1. The space it occupies
    2. Measure: litres
2. Specific properties
  1. Density
    1. Amount of mass that lifs into a certain volume
  2. Hardness
    1. Resistance of a substance against being scratched.
  3. Tenacity
    1. Is the opposition a material has against breaking or becoming deformed.
  4. Transparency
    1. It allow light to pass through it.
  5. Impermeability
    1. It prevent water from passing through it.
  6. Lightness
    1. It is the ease with which a body can be lifted.
  7. Thermal or electric conductivity
    1. It is the ability to conduct heat or electricity.
  8. Thermal or electric insulation
    1. It prevent heat or electricity from passing through it.
  9. Colour, flavour and smell
    1. They are perceptibles by the senses.
Pure Substances and mixtures
1. Pure substances
  1. One single type of element
2. Mixtures
  1. Made up of two or more elements
  2. 2 tipes
    1. Heterogeneous mixture
      1. Elements are distinguished
    2. Homogenous mixture
      1. Elements are not distinguished
3. Separate mixtures
  1. Filtration
    1. Separate solid-liquid.
  2. Decantation
    1. Separate components (heterogeneous mixture) by the density.
  3. Magnetic separation
    1. Separate iron or steel from a mixture.
  4. Distilation
    1. Separate two liquids with different boiling point.
  5. Evaporation
    1. Separate components of a liquid solution.
