1. What are the 3 states of matter we are studying?
Answer: C) Solids, Liquids, and Gases
✔ Explanation: The three primary states of matter are solid, liquid, and gas. These are the forms in which matter commonly exists under normal conditions.
---
2. Fill the blank: In a ________, particles are packed closely together and are not free to move within the substance.
Answer: A) Solid
✔ Explanation: In solids, particles are tightly packed in a fixed arrangement and vibrate in place but do not move freely. This gives solids a definite shape and volume.
---
3. What properties do we look at to figure out which state of matter an object is?
Answer: D) Shape, Mass, Volume
✔ Explanation: To identify the state of matter, we observe physical properties like:
-
Shape: Solids have a definite shape; liquids take the shape of their container; gases fill the entire container.
-
Volume: All states have volume, but only solids and liquids have fixed volumes (gases expand).
-
Mass: Helps determine density, which varies between states.
The scientific method or hypothesis isn’t a property — it’s a process.

4. Is a computer a solid, liquid, or a gas?
Answer: C) Solid
✔ Explanation: A computer is made of solid materials (plastic, metal, circuit boards). It maintains a definite shape and volume, so it is classified as a
solid.

5. What are water and oil examples of?
Answer: D) Liquids
✔ Explanation: Both water and oil flow, take the shape of their container, and have a definite volume — all characteristics of
liquids.
---
6. True or False: "In a liquid, the particles are close and slide past each other."
Answer: A) TRUE
✔ Explanation: In liquids, particles are close together but not fixed in position. They can move past one another, allowing liquids to flow. This is why they are fluid.
---
7. Does liquid have a definitive shape?
Answer: A) FALSE
✔ Explanation: Liquids
do not have a definite shape. They take the shape of the container they are in, although they do have a definite volume.

✔ Final Answers Summary:
| Question | Answer | Explanation |
|--------|--------|------------|
| 1 | C | Solids, Liquids, and Gases are the three states of matter. |
| 2 | A | Solids have tightly packed particles that don't move freely. |
| 3 | D | Shape, mass, and volume help identify the state of matter. |
| 4 | C | A computer is a solid object. |
| 5 | D | Water and oil are both liquids. |
| 6 | A | TRUE — liquid particles are close and can slide past each other. |
| 7 | A | FALSE — liquids do not have a definite shape. |
