PROPERTIES AND CHANGES
Keep this in your binder as a study guide!
Background: Keeping the difference between physical and chemical properties as well as changes can be a
challenge! This worksheet will help you do this. First, use the book to define the following terms.
Characteristics of matter that can be seen through direct observation such as
density, melting point, and boiling point
Change in which the identity of the substance does NOT change
Characteristic of matter that can only be observed when one substance changes
into a difference substance, such as iron into rust
Transforms one type of matter into another kind, which may have different
properties.
Part One: Physical or Chemical Property? Fill in the chart using the vocabulary words or phrases provided.
