The image shows an educational worksheet titled
"States of Water", designed to help students understand the three states of water:
ice (solid),
water (liquid), and
water vapour (gas). The task is to complete a table using these terms to describe the changes in state.

🔍 Understanding the Process
Water can change from one state to another through physical processes:
-
Freezing: Liquid water turns into solid ice.
-
Melting: Solid ice turns into liquid water.
-
Evaporation: Liquid water turns into water vapour (gas).
-
Condensation: Water vapour turns into liquid water.
These are phase changes and are reversible.

✔ Step-by-Step Solution
We need to fill in the table with the correct starting and ending states for each process.
| Process | From | To |
|----------------|---------------|---------------|
| Freezing | water | ice |
| Melting | ice | water |
| Evaporation | water | water vapour |
| Condensation | water vapour | water |

🧠 Explanation
1.
Freezing
- When water cools down below 0°C, it becomes
ice.
→ So,
water → ice
2.
Melting
- When ice is heated above 0°C, it turns into
water.
→ So,
ice → water
3.
Evaporation
- When water is heated, it turns into
water vapour (invisible gas).
→ So,
water → water vapour
4.
Condensation
- When water vapour cools down, it turns back into
liquid water (e.g., dew on grass).
→ So,
water vapour → water

✔ Final Answer (Completed Table)
| Process | From | To |
|----------------|---------------|---------------|
| Freezing | water | ice |
| Melting | ice | water |
| Evaporation | water | water vapour |
| Condensation | water vapour | water |
This completes the worksheet correctly using the words:
ice, water, water vapour.
