Properties of Matter: Study Guide Answer Key
1. What is mass often measured in? grams or kilograms.
2. Which particle has a negative electrical charge? Positive charge? A proton has a positive
charge. An electron has a negative charge. Neutrons have no charge
3. What are the properties of a solid? A liquid? A gas? Solid: has a definite shape and volume;
Liquid: definite volume but no definite shape; Gas: no definite volume; no definite shape.
4. What tools might be used to measure the mass of an object? A balance
5. How are the physical properties of a cup of lemonade and a pitcher of lemonade alike? How
are they different? The cup of lemonade and pitcher of lemonade have different mass,
weight, and shape. They also have different volume. They are both the same color and are a
liquid.
6. What is a conductor? An insulator? Conductor - a material that electricity can move through
easily. Metals are the best conductors. Insulators - materials that can stop most electricity from
passing through. Examples of an insulator are rubber and plastic.
7. All of the gases, liquids, and solids in the world are made up of matter.
8. The amount of matter in an object is its mass.
9. The amount of space an object takes up is volume.
10. A measure of the force of gravity between Earth and an object is the object’s weight.
11. Matter in which particles line up pole to pole is magnetism.
12. What is the difference between physical and chemical changes? Give an example of each.
A physical change is a change from one state (solid or liquid or gas) to another without a
change in chemical composition. Example: condensation, cutting paper, freezing water,
breaking glass
A chemical change is the result of a reaction which creates one or more substances with
different chemical properties. Example: Cake baking (you are combining several ingredients
into a solution, adding heat and making a new material that cannot be returned into the
original ingredients), burning paper/wood, rusting

14. Draw and label a carbon atom (with 6 protons, 6 electrons, & 6 neutrons). Be sure to label its
protons, neutrons, and electrons.
