of matter.

Review
Name two categories used to classify properties of matter.
Explain why all samples of a substance have the same intensive properties.
Name three states of matter.Describe the two categories used to classify
physical changes
Review cont…Use Table 2.1 to distinguish between Sodium
Chloride from other solids.Compare and contrast solids, liquids and
gasesGive examples of reversible and irreversible
physical changes.Give an example of two different substances
having the same extensive properties.Can two substances have the same set of
intensive properties?
