Now, let’s go through each question and fill in the correct answers with explanations.

---

1. The three basic properties of matter are ____________, ____________, and ____________.

✔ Answer: *mass*, *volume*, *shape*

Explanation:
All matter has mass (amount of matter), volume (space it takes up), and shape (form it occupies). These are the three fundamental physical properties.

---

2. All matter is made up of tiny particles called ____________.

✔ Answer: *atoms*

Explanation:
Matter is composed of small, invisible particles known as atoms. Everything around us—solids, liquids, gases—is made of atoms.

---

3. Volume is the amount of ____________ that matter takes up.

✔ Answer: *space*

Explanation:
Volume refers to how much space an object or substance occupies. For example, a large ball has more volume than a small one.

---

4. Mass is the amount of ____________ an object has.

✔ Answer: *matter*

Explanation:
Mass measures how much matter is in an object. It does not change with location (unlike weight).

---

5. Liquids take the shape of their ____________.

✔ Answer: *container*

Explanation:
Liquids do not have a fixed shape; they flow and take the shape of the container they are in (e.g., water in a cup).

---

6. ____________ do not have a definite shape or volume.

✔ Answer: *gases*

Explanation:
Gases expand to fill their container. They have no fixed shape or volume (e.g., air, oxygen).

---

7. ____________ do not have a definite shape, but they have a definite volume.

✔ Answer: *liquids*

Explanation:
Liquids flow and take the shape of their container, but they keep the same amount of volume (they don’t compress easily).

---

8. ____________ have a definite shape and volume.

✔ Answer: *solids*

Explanation:
Solids maintain their shape and volume because their particles are tightly packed and vibrate in place.

---

9. A ____________ and ____________ are examples of solids.

✔ Answer: *chair* and *ice*

Explanation:
Both a chair and ice are solid objects—they hold their shape and volume.

> Note: "Ice" is also a solid form of water, so it fits perfectly here.

---

10. ____________ and ____________ are examples of liquids.

✔ Answer: *juice* and *milk*

Explanation:
Juice and milk are common liquids—they flow and take the shape of their containers.

---

11. ____________ and ____________ are examples of gas.

✔ Answer: *oxygen* and *helium*

Explanation:
Oxygen is a gas we breathe, and helium is a gas used in balloons. Both are invisible and expand to fill space.

---

12. Solid ice is ____________ when it is changing into a liquid.

✔ Answer: *melting*

Explanation:
Melting is the process where a solid turns into a liquid due to heat (e.g., ice turning into water).

---

✔ Final Answers:

1. mass, volume, shape
2. atoms
3. space
4. matter
5. container
6. gases
7. liquids
8. solids
9. chair, ice
10. juice, milk
11. oxygen, helium
12. melting
