Worksheet Analysis and Solutions

#### 1. Matter is anything that has ________ (mass, volume, length, color).
- Solution: Matter is defined as anything that has mass and takes up space (volume). While color can be a property of matter, it is not a defining characteristic.
- Answer: mass

#### 2. Give three examples of matter: ________, ________, ________.
- Solution: Matter includes anything that occupies space and has mass. Examples include solids, liquids, and gases.
- Answer: water, air, wood

#### 3. All of the matter on Earth is made up of tiny particles called ________.
- Solution: Matter is composed of tiny building blocks called atoms. Atoms are the basic units of matter.
- Answer: atoms

#### 4. A substance is formed when two or more elements combine chemically to form a new material. An example of a substance is ________.
- Solution: A substance is a pure material with a fixed composition, such as water (H₂O), which is formed by combining hydrogen and oxygen.
- Answer: water

#### 5. In its solid form, matter has a definite shape and ________.
- Solution: Solids have both a definite shape and a definite volume because their particles are closely packed and vibrate in place.
- Answer: volume

#### 6. For the liquid state, matter has a definite ________ but no definite shape.
- Solution: Liquids have a definite volume because they occupy a specific amount of space, but they take the shape of their container.
- Answer: volume

#### 7. An example of a gas is ________.
- Solution: Gases are substances that have neither a definite shape nor a definite volume. They expand to fill any container. Air is a common example of a gas.
- Answer: air

#### 8. A property of matter is a characteristic or quality of matter. An example of a physical property is ________.
- Solution: Physical properties are characteristics that can be observed or measured without changing the identity of the substance. Examples include color, density, hardness, and melting point.
- Answer: color

#### 9. A property of matter is a characteristic or quality of matter. An example of a chemical property is ________.
- Solution: Chemical properties describe how a substance reacts or changes into other substances. Examples include flammability, reactivity with acids, and rusting.
- Answer: flammability

#### 10. Properties of matter can be used to ________ materials.
- Solution: Properties of matter help identify, classify, and separate materials. For example, density can be used to distinguish between different substances.
- Answer: identify

#### 11. Some properties of matter depend on the amount of matter present. These are called ________ properties.
- Solution: Extensive properties depend on the amount of matter, such as mass, volume, and energy. Intensive properties, on the other hand, do not depend on the amount of matter.
- Answer: extensive

#### 12. Properties of matter that do not depend on the amount of matter present are called ________ properties.
- Solution: Intensive properties are independent of the amount of matter, such as density, boiling point, and freezing point.
- Answer: intensive

#### 13. A change in which the properties of a substance remain the same is called a ________ change.
- Solution: Physical changes involve changes in the state or form of matter without altering its chemical composition. Examples include melting, freezing, and dissolving.
- Answer: physical

#### 14. A change in which a substance is converted into another substance is called a ________ change.
- Solution: Chemical changes involve the formation of new substances with different properties. Examples include burning, rusting, and cooking.
- Answer: chemical
