What is filtration?

• Uses a porous barrier to allow some

  materials through while holding others

  back.

• This is based on a difference

  in boiling points. The solution is heated

  and the more volatile substance turns to

  gas leaving the other behind.

• Separation that results in the formation

  of a a pure solid particle from a solution

  containing it.

• Common lab procedure to separate

  individual components based on their

  attractiveness to a solvent.

What is distillation?

• Uses a porous barrier to allow some

  materials through while holding others

  back.

• This is based on a difference

  in boiling points. The solution is heated

  and the more volatile substance turns to

  gas leaving the other behind.

• Separation that results in the formation

  of a a pure solid particle from a solution

  containing it.

What is heterogenous?

• distinct differences are still evident

  throughout.

• the mixture is the same throughout.

What is a solid?

• cannot be easily compressed or

  shape changed. Definite volume and

  shape.

• definite volume, takes on the

  shape of its container.

• both volume and shape are

  determined by the container.

• something that is a solid or

  liquid at room temperature, but has been

  changed to the gaseous state.
