Question

Accepted Answer

# Explanation:
## Step1: Recall property - type classification
Intensive and extensive properties are used to describe matter.
1. intensive property; 2. extensive property
## Step2: Recall mass definition
Mass measures amount of matter.
3. mass
## Step3: Recall volume definition
Volume measures space occupied by object.
4. volume
## Step4: Recall extensive - property dependence
Extensive property depends on amount of matter.
5. amount
## Step5: Recall intensive - property dependence
Intensive property depends on type of matter.
6. type
## Step6: Recall substance definition
Substance has uniform and definite composition.
7. substance
## Step7: Recall solid properties
Solid has definite shape and volume.
8. shape; 9. volume
## Step8: Recall liquid properties
Liquid has definite volume and takes shape of container.
10. shape
## Step9: Recall gas properties
Gas takes shape and volume of container.
11. gas

# Answer for Part B:
11. AT; Matter is defined as anything that has mass and occupies space.
12. NT; Liquids take the shape of their container and do not have a definite shape on their own.
13. ST; It depends on the melting - point of the solid. Some solids have melting - points above 200°C.
14. AT; Gases have more space between their particles compared to liquids, making them easier to compress.

# Answer for Essay Writing (brief samples):
- **Properties of a solid**: Solids have a definite shape and volume. The particles in a solid are closely packed and vibrate in place.
- **Properties of a liquid**: Liquids have a definite volume but take the shape of their container. The particles in a liquid are close together but can move past one another.
- **Properties of a gas**: Gases have no definite shape or volume and take the shape and volume of their container. The particles in a gas are far apart and move freely.
- **How temperature affects solids**: Increasing temperature can cause a solid to expand and, if the melting - point is reached, to change into a liquid (melting). Decreasing temperature can cause a solid to contract.
- **How temperature affects liquids**: Increasing temperature can cause a liquid to expand and, if the boiling - point is reached, to change into a gas (boiling). Decreasing temperature can cause a liquid to contract and, if the freezing - point is reached, to change into a solid (freezing).
- **What is meant by changes of state**: Changes of state are physical changes in which matter changes from one state (solid, liquid, gas) to another without changing its chemical composition.
- **Describe changes of state in solids, liquids and gases**: Solids can melt into liquids, liquids can freeze into solids, liquids can vaporize into gases, gases can condense into liquids, solids can sublime into gases, and gases can deposit into solids.
- **Compare and contrast the three types of matter**: Solids have fixed shape and volume, liquids have fixed volume but variable shape, and gases have variable shape and volume. All three are made of particles, but particle spacing and movement differ.
- **Classify at least 5 liquids, solids and gases**:
  - **Liquids**: Water, milk, oil, alcohol, vinegar.
  - **Solids**: Iron, wood, ice, salt, sugar.
  - **Gases**: Oxygen, nitrogen, carbon - dioxide, helium, hydrogen.
