Characteristic properties of_matter

1. Characteristic Properties of Matter

2. Characteristic Properties of Matter—The Key Ideas Matter is anything that has mass and takes up space.

3. Characteristic Properties of Matter—The Key Ideas Matter has characteristic properties that can be divided into physical properties and chemical properties.

4. Characteristic Properties of Matter—The Key Ideas The physical properties of matter include color, odor, density, solubility, melting point, boiling point, and electrical conductivity. These are properties that can be observed without chemically changing the substance.

5. Characteristic Properties of Matter—The Key Ideas The characteristic chemical properties of matter include acidity, basicity, combustibility, and reactivity. In order to learn about the chemical properties of a substance, an attempt must be made to chemically change it.

6. Characteristic Properties of Matter—The Key Ideas Characteristic properties of matter do not depend on the amount of matter that makes up an object, or on the shape of the object.

7. Characteristic Properties of Matter—The Key Ideas Some factors that can change the characteristic properties of matter are heat, temperature, pressure, electromagnetic energy, and nuclear processes.

8. Characteristic Properties of Matter— • Size, volume, and mass are characteristic properties of matter. – Reality: The amount of matter in an object does not affect the characteristic properties of the object.• Shape is a characteristic property of matter. – Reality: An object will retain all of its characteristic properties regardless of its shape. For example, the water in a faucet and the water in a bucket are both clear and colorless, have a boiling point at 100ºC, can dissolve table salt, etc. Note, however, that the shape of crystals will follow the same pattern regardless of size, and this pattern is a chemical property.

9. Characteristic Properties of Matter— Common Misconceptions • Boiling and freezing are chemical changes. – Reality: Boiling and freezing are physical changes that make the molecules of a substance move faster or slower and be closer or farther apart. However, the molecules are not changed chemically.• Air and other gases are not a type of matter. – Reality: Gases are a type of matter because they have mass and take up weight. To have students experience how air takes up space, inflate a balloon or plastic bag and have students try to squeeze it.
