Properties of Matter Handout Worksheet | Science 7th Grade - Free Printable

The task involves filling in the blanks with the appropriate terms related to the properties of matter. Let's solve it step by step:

---

Section 1: Physical Properties of Matter

These are characteristics that can be observed or measured without changing the identity of the substance.

1. a characteristic or description of a substance that may help you to identify it (does not involve a substance becoming a new substance)
- Answer: Physical Property

2. measure of the resistance of a solid to being scratched or dented
- Answer: Hardness

3. the ability to be hammered into thin sheets (alternative: brittle)
- Answer: Malleability

4. the ability to be pulled into wires
- Answer: Ductility

5. the temperature at which the substances change state
- Answer: Melting Point/Boiling Point (depending on the specific context, but generally "Melting Point" is more common for solids)

6. solid form of many minerals in which you can see a definite structure of cubes or blocks with a regular pattern
- Answer: Crystal Structure

7. the ability of a substance to dissolve in a solvent, such as water
- Answer: Solubility

8. how easily a liquid flows
- Answer: Viscosity

9. the amount of matter for unit volume of that matter
- Answer: Density

Section 2: Chemical Properties of Matter

These are characteristics that describe how a substance reacts or changes into a new substance.

10. the behavior of a substance as it becomes a new substance
- Answer: Chemical Property

11. the ability of a substance to react with oxygen to produce carbon dioxide
- Answer: Flammability/Combustibility

12. the ability of a substance to react with an acid
- Answer: Acid Reactivity/Acid Base Reaction

13. the substance will produce rust
- Answer: Reactivity with Oxygen/Rusting/Oxidation
