a) Homogeneous (Solutions)
Solid – definite volume and shape; particles packed in fixed positions.
Liquid – definite volume but indefinite shape; particles close together but not in fixed positions
Gas – neither definite volume nor definite shape; particles are at great distances from one another

Energy Content (think Calories!)
Extensive properties depend on the amount of matter that is present.
Intensive properties do not depend on the amount of matter present.
The constituents of the mixture retain their identity and may be separated by physical means.
Separation of a Mixture
The components of dyes such as ink may be separated by paper chromatography.
The Electrolysis of water
Water Hydrogen + Oxygen
2 H2O 2 H2 + O2
Compounds must be separated by chemical means.
With the application of electricity, water can be separated into its elements
