To solve this problem, we need to classify the changes of state depicted in each image using the provided terms:
melting,
evaporation,
solidification, and
condensation. Let's analyze each scenario step by step:
---
1. Ice cream in the summer
-
Description: Ice cream is a solid that melts when exposed to heat (e.g., warm summer temperatures).
-
Change of state: Solid → Liquid
-
Term:
Melting
---
2. Water boiling
-
Description: When water boils, it turns into steam (water vapor), which is a gas.
-
Change of state: Liquid → Gas
-
Term:
Evaporation
---
3. Lava turns into rock
-
Description: Lava is molten rock (liquid) that cools down and hardens into solid rock.
-
Change of state: Liquid → Solid
-
Term:
Solidification
---
4. Drying clothes
-
Description: Wet clothes have water on them. As the water evaporates, the clothes dry.
-
Change of state: Liquid → Gas
-
Term:
Evaporation
---
5. Creation of clouds
-
Description: Clouds are formed when water vapor in the air cools down and condenses into tiny droplets of liquid water.
-
Change of state: Gas → Liquid
-
Term:
Condensation
---
6. Fusing steel
-
Description: Fusing involves heating metal (steel) until it melts and then cooling it to form a solid structure.
-
Change of state: Solid → Liquid → Solid
-
Term:
Melting (initially) and
Solidification (finally). However, since only one term can be chosen, we focus on the primary change:
Melting.

Final Answers:
- Ice cream in the summer:
Melting
- Water boiling:
Evaporation
- Lava turns into rock:
Solidification
- Drying clothes:
Evaporation
- Creation of clouds:
Condensation
- Fusing steel:
Melting
---
