Properties Of Matter

• Chemistry
• Study of the properties of matter
• How matter changes
• The properties change for any type of matter
  depends on its makeup.
• Substance
• Single kind of matter
• Each form of matter has two kinds of properties.

3

• Physical property
• Characteristic of a pure substance that can be
  observed without changing it into another
  substance.
• Chemical Property
• Characteristic of pure substance that describes
  its ability to change.

4
Elements

• Elements
• Cant be broken down
• Simplest substances
• Atoms
• Basic particle from which all elements are made.
• Chemical Bond
• Force of attraction between two atoms.
• Molecules
• Groups of two or more atoms held together by
  Chemical bond.

5
Compounds

• All matter is an element.
• Compounds
• Pure substance made of two or more elements.
• Chemical Formula
• Shows elements
• When elements are chemically combined, they form
  compound living properties that are different
  from those of the uncombined elements.

6
Mixtures

• Elements and compound are pure substances.
• Mixture
• Made of two or more
• Elements
• Compound
• Each substance in a mixture keeps its individual
  properties.
• The parts of a mixture are not combined in a set
  ratio.

7

• Homogeneous Mixture
• Mixed
• Cant see the difference
• Solution
• Example of homogeneous mixture
• Solutions doesnt have to be liquids.
• Compounds and mixture differ in yet another way.

8

• Compound
• Difficult to separate into its element.
• Mixture
• Easy to separate into its compound because each
  compound keeps its own properties.
