Let’s go through each sentence one by one and think about what happens to water when it changes state.
---
1. Ice changes to water when it is ________.
Ice is solid water. When you warm up ice, it melts and becomes liquid water. So, we say it is
heated.
→ Answer: heated
---
2. Water changes to water vapor when it is ________.
Water vapor is the gas form of water (like steam). To turn liquid water into gas, you need to heat it — like boiling water on a stove. So, again, it’s
heated.
→ Answer: heated
---
3. Water vapor changes to water when it is ________.
When water vapor cools down, it turns back into liquid water — this is called condensation. For example, when you see drops on a cold drink can, that’s water vapor turning to water because it got cooled. So, it’s
cooled.
→ Answer: cooled
---
4. Water changes to ice when it is ________.
Liquid water turns into solid ice when it gets very cold — like in a freezer. So, we say it is
cooled.
→ Answer: cooled
---
Final Answer:
- Ice changes to water when it is
heated.
- Water changes to water vapor when it is
heated.
- Water vapor changes to water when it is
cooled.
- Water changes to ice when it is
cooled.
