Worksheet on the three forms of matter: solid, liquid, and gas.

Problem Overview:

The task involves answering questions based on the provided passage about the forms of matter. The passage discusses the properties and characteristics of solids, liquids, and gases. Below is a detailed explanation and solution for each question.

---

Passage Summary:

- Solids: Have a definite shape and volume. Their particles are packed closely together and vibrate in place but do not move freely.
- Liquids: Have a definite volume but take the shape of their container. Their particles are close together but can slide past each other.
- Gases: Have neither a definite shape nor a definite volume. Their particles are far apart and move freely.

Questions and Solutions:

#### 1. What does the word "properties" mean in the first paragraph?
- Explanation: In the context of the passage, "properties" refers to the characteristics or attributes that define how matter behaves under different conditions. These properties help scientists classify and understand matter.
- Answer: Characteristics or attributes that define how matter behaves.

#### 2. What are the three forms that matter can take?
- Explanation: The passage explicitly mentions three forms of matter: solid, liquid, and gas.
- Answer: Solid, liquid, and gas.

---

#### 3. What does the word "vibrate" mean in the second paragraph?
- Explanation: In the context of the passage, "vibrate" means that the particles in a solid move back and forth in place but do not change their relative positions. This movement is due to the energy they possess.
- Answer: Move back and forth in place without changing position relative to each other.

---

#### 4. What is one difference between a solid and a liquid?
- Explanation: The key difference highlighted in the passage is that solids have a definite shape, while liquids take the shape of their container. Additionally, the particles in a solid are packed closely together and vibrate in place, whereas the particles in a liquid can slide past each other.
- Answer: Solids have a definite shape, while liquids take the shape of their container.

#### 5. Are the tiny particles closer together in a solid, a liquid, or a gas?
- Explanation: The passage explains that particles in a solid are packed closely together, particles in a liquid are close but can slide past each other, and particles in a gas are far apart. Therefore, particles are closest together in a solid.
- Answer: Particles are closer together in a solid.

Final Answers:

1. Characteristics or attributes that define how matter behaves.
2. Solid, liquid, and gas.
3. Move back and forth in place without changing position relative to each other.
4. Solids have a definite shape, while liquids take the shape of their container.
5. Particles are closer together in a solid.
