Step-by-step solution for: Change states worksheet
Let's solve each question step by step using the word bank provided:
Word Bank:
Freezing point, ice cubes, melting point, temperature, boil, matter, Boiling point, volume, shape, particles
---
Answer: *Matter*
Explanation: Matter is anything that has mass and takes up space. All matter can change states — solid → liquid → gas — depending on temperature.
✔ Correct answer: matter
---
Answer: *ice cubes*
Explanation: When water freezes, it becomes solid ice. Ice cubes are a common example of frozen water.
✔ Correct answer: ice cubes
---
Answer: *Freezing point*
Explanation: The freezing point is the temperature at which a liquid turns into a solid. For water, this is 0°C.
✔ Correct answer: freezing point
---
Answer: *Melting point*
Explanation: The melting point is the temperature at which a solid becomes a liquid. For water, this is also 0°C.
✔ Correct answer: melting point
---
Answer: *temperature*
Explanation: At 100°C, water reaches its boiling point and turns into steam (gas). This happens when the temperature rises to that level.
✔ Correct answer: temperature
---
Answer: *boil*
Explanation: Boiling is the process where liquid water turns into vapor (gas) at 100°C under standard pressure.
✔ Correct answer: boil
---
Answer: *Boiling point*
Explanation: The boiling point is the specific temperature at which a liquid turns into a gas.
✔ Correct answer: boiling point
---
Answer: *particles*
Explanation: In solids, particles are tightly packed and vibrate in place — they move much more slowly than in liquids or gases.
✔ Correct answer: particles
---
Answer: *volume*
Explanation: Liquids take the shape of their container but maintain a fixed volume. They do not have a definite shape, but they do have a definite volume.
✔ Correct answer: volume
---
Answer: *shape*
Explanation: Solids keep their shape and volume because their particles are tightly packed and don't flow.
✔ Correct answer: shape

1. ________ can go from solid to liquid to gas.
Answer: *Matter*
Explanation: Matter is anything that has mass and takes up space. All matter can change states — solid → liquid → gas — depending on temperature.
✔ Correct answer: matter
---
2. You change water to a solid when you make ________.
Answer: *ice cubes*
Explanation: When water freezes, it becomes solid ice. Ice cubes are a common example of frozen water.
✔ Correct answer: ice cubes
---
3. ________ is the temperature at which a substance changes from its liquid state to its solid state.
Answer: *Freezing point*
Explanation: The freezing point is the temperature at which a liquid turns into a solid. For water, this is 0°C.
✔ Correct answer: freezing point
---
4. ________ is the temperature at which a solid changes to a liquid.
Answer: *Melting point*
Explanation: The melting point is the temperature at which a solid becomes a liquid. For water, this is also 0°C.
✔ Correct answer: melting point
---
5. Water changes into steam (a gas), when its ________ reaches 100 Celsius.
Answer: *temperature*
Explanation: At 100°C, water reaches its boiling point and turns into steam (gas). This happens when the temperature rises to that level.
✔ Correct answer: temperature
---
6. You change water into a gas when you ________ water.
Answer: *boil*
Explanation: Boiling is the process where liquid water turns into vapor (gas) at 100°C under standard pressure.
✔ Correct answer: boil
---
7. ________ of a substance is the temperature when a substance changes from a liquid to a gas.
Answer: *Boiling point*
Explanation: The boiling point is the specific temperature at which a liquid turns into a gas.
✔ Correct answer: boiling point
---
8. In a solid the ________ move even slower.
Answer: *particles*
Explanation: In solids, particles are tightly packed and vibrate in place — they move much more slowly than in liquids or gases.
✔ Correct answer: particles
---
9. A liquid does have a ________ of its own.
Answer: *volume*
Explanation: Liquids take the shape of their container but maintain a fixed volume. They do not have a definite shape, but they do have a definite volume.
✔ Correct answer: volume
---
10. Solids have definite ________.
Answer: *shape*
Explanation: Solids keep their shape and volume because their particles are tightly packed and don't flow.
✔ Correct answer: shape
---
✔ Final Answers:
1. matter
2. ice cubes
3. freezing point
4. melting point
5. temperature
6. boil
