Classification of Matter Notes
🔬 Classification of Matter
Matter is anything that has mass and takes up space. It can be classified
in two main ways:
I. Physical State (based on shape and volume)
Stat Compressibilit
Shape Volume
e y
Solid Fixed Fixed Incompressible
Liqui Takes container Slightly
Fixed
d shape compressible
Takes container Fills entire
Gas Compressible
shape container
II. Composition (based on what matter is made of)
A. Pure Substances
Have a fixed composition.
Cannot be separated by physical means.
Every sample has the same properties.
Types of Pure Substances:
1. Elements
o Cannot be broken down into simpler substances.
o Found on the Periodic Table.
o Examples: Oxygen (O₂), Iron (Fe), Gold (Au)
2. Compounds
o Made of two or more elements chemically combined.
o Have a fixed ratio and can be broken down chemically.
o Examples: Water (H₂O), Carbon dioxide (CO₂), Sodium chloride
(NaCl)
