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?
