Matter and Its Interactions
Study online at https://quizlet.com/_huluc9
1. What is matter?: All the substances that make up everything in the
universe are forms of matter. Each pure substance has
characteristic properties—both physical and chemical.
All matter has mass.
2. What are some examples of chemical changes you might
observe in your everyday life?: Physical changes do not result in the formation of a new substance.
Chemical changes differ from the original substance. Some chemical changes are
rusting, digestion, baking, and combustion. All of these create a new substance.
3. What are some physical properties you observed during this unit?: Physical
changes do not result in new
substances. The atoms and molecules in the original
substance remain the same. Some examples are dissolving, melting, freezing, boiling, condensing, and cutting. The
observable physical properties of the substance remains the same.
4. What can properties of matter help you determine?: I can use characteristic physical and
chemical
properties to identify substances.
I can collect data related to physical and chemical properties before and after substances interact.
I can analyze and interpret this data to determine similarities and differences before and after substances interact.
If characteristic properties differ, a chemical reaction has occurred and resulted in the formation of a new substance.
5. How can illustrations and diagrams be helpful for communicating ideas?: Illus-
trations and diagrams can be helpful for
communicating ideas because they can represent complex ideas and explanations in a visual way.
6. How can density be used to identify a substance and predict how it will behave
under different conditions?: The density of a substance is a characteristic property. If the density of two
substances is the same, they might be the same substance. Density can also be used to predict if a solid object will sink
or float, or if an immiscible liquid (liquids that don't mix together) will be layered above or below another liquid.
Density is a characteristic property and that it can be used to predict layering, floating, and sinking.
