UNIT 1: Matter

• Chemistry is a branch of science that deals the study of matter.
• process of removing solid particles from filtering medium

  Filtration
• solid particles from filtration medium

  Residue
• clear liquid passes from the filtration medium

  Filtrate
• some solids of a suspension mixture are allowed to settle & the less dense mats are poured off.

  Decantation or Flotation
• speeding up the settling precipitate.

  Centrifugation
• evaporating/condensing a volatile liquid

  Distillation
• liquid formed from condensation of vapor

  Distillate
• separating a liquid mixture using boiling points

  Fractional Distillation
• lowers the temp to get more insoluble crystallizes out first

  Crystallization
• uses different degree to which the substances are absorbed on the surface of an inert substance.

  Chromatography
• Matter 


  anything that occupies space.
• Molecules are group of atoms.
• Ions carry charges to atoms/molecules.
• States of Matter

  Solid, Liquid, Gas
• Properties of Matter

  Physical, Chemical
• Intensive


  the value is constant when the amount of matter is changed.
• Extensive


  the value changes when the amount of matter is changed.
• Pure Substance composed of only one component.
• Elements are made up of only one kind of atom.
• Compounds are made up of two or more kinds of atoms.
• Mixtures are composed of several components.
• Homogeneous Mixture has uniform composition throughout
• Heterogenous Mixture does not have uniform composition throughout
• Volume measures how much space the object occupies.
• Freezing


  liquid to solid
• Melting


  Solid to liquid
• Evaporation


  Liquid to Gas
• Condensation


  Gas to Liquid
• Sublimation


  Solid to Gas
• Deposition


  Gas to Solid
