  • Compose one or more pure substances in different particles.
    mixtures
  • vinegar homogenous or heterogenous?
    homogenous
  • is a technique that is used in separating a mixture, usually a solution of a solvent and a soluble solid.
    evaporation
  • oil in water homogenous or heterogenous?
    heterogenous
  • heterogenous or homogenous? blood
    homogenous
  • homogenous or heterogenous?
    homogenous
  • Content has a uniform appearance
    homogeneous
  • Components of the mixture can't be seen separately.
    homogeneous
  • is the technique of separating an insoluble solid and a liquid by pouring the mixture into a filter paper. 
    Filtration
  • homogenous or heterogenous
    heterogenous
  • Content has a visibly different appearance/ visually distinguishable components.
    heterogeneous
  • methods are used for the separation of insoluble substances which are heavier than liquid.
    sedimentation
  • what kind of pure substances is this?
    golden rings
  • Four techniques in separating solid mixture.
    winnowing, handpicking, sieving, magnet
  • a farming method developed by ancient people for separating grain from the chaff or husk from the grains by wind/air.
    winnowing
  • A method in which substances in a mixture can be separated by just picking them out with the help of a hand from the mixture.
    handpicking
  • In this process, heavier components of the mixture settle on the bottom, due to gravity.
    sedimentation
  • Content can be seen separately.
    heterogeneous
  • in this method, the solution is heated until the organic solvent evaporates where it turns into a gas and mostly leaves behind the solid residue.
    evaporation
  • a method of separation which is used for separating solid components of different sized that are difficult to handpick by using sifting with a sieve.
    sieving
  • the process of separating components of mixtures by using a magnet to attract magnetic substances.
    magnet
  • what kind of pure substances is this?
    water
  • what kind of pure substances is this?
    salt
  • three techniques in separating insoluble solid from liquid .
    filtration, sedimentation, evaporation
