Problem Analysis:
The task involves matching terms related to the states of matter and phase changes with their correct descriptions. The words provided are:
condensation, deposition, evaporation, freezing, gas, liquid, melting, solid, sublimation, vapor. Each word must be used only once.
Solution:
Let's solve each question step by step:
---
####
1. The phase change from gas to liquid is called ______.
- When a gas transforms into a liquid, it undergoes
condensation.
-
Answer: condensation
---
####
2. Ice is in the ______ phase of water.
- Ice is the solid form of water.
-
Answer: solid
---
####
3. This phase of water is flexible.
- Water in its liquid state is flexible (e.g., it can flow).
-
Answer: liquid
---
####
4. Occurs when energy is added to a liquid water.
- Adding energy to liquid water causes it to evaporate, turning into vapor.
-
Answer: vapor
---
####
5. Frost is an example of ______.
- Frost forms when water vapor directly turns into ice (solid) without passing through the liquid phase. This process is called
deposition.
-
Answer: deposition
---
####
6. Ice will ______ when energy is added to it.
- When energy is added to ice (solid water), it melts into liquid water.
-
Answer: melt
---
####
7. The phase change from solid directly to gas is called ______.
- The direct transformation of a solid into a gas is called
sublimation.
-
Answer: sublimation
---
####
8. When liquid water loses energy, it turns into ______.
- When liquid water loses energy, it cools down and freezes into ice (solid).
-
Answer: solid
---
####
9. When water vapor cools, it turns into ______.
- When water vapor (gas) cools, it condenses into liquid water.
-
Answer: liquid
---
####
10. Describe the arrangement of the water molecules in their solid form.
- In the solid form of water (ice), water molecules are arranged in a fixed, ordered structure. They form a crystalline lattice where each molecule is bonded to four neighboring molecules in a tetrahedral arrangement. This rigid structure gives ice its solid properties.
-
Answer: Water molecules in ice are arranged in a fixed, ordered crystalline lattice.
