Educational worksheet illustrating the states of water and their transitions.

Let’s go step by step to fill in the table correctly.

We are given a list of changes of state and need to say:
1. What change occurs (like solid → liquid, etc.)
2. Whether heat is absorbed or released during that change.

---

Condensation
This is when gas turns into liquid (like water vapor turning into dew).
→ Change: Gas → Liquid
→ Heat is released (because molecules slow down and come together)

Deposition
This is when gas turns directly into solid (like frost forming from water vapor in air).
→ Change: Gas → Solid
→ Heat is released

Evaporation
Already filled: Liquid → Gas
Heat absorbed — correct! (molecules need energy to escape as gas)

Melting
Already filled: Solid → Liquid
Heat absorbed — correct! (ice needs heat to turn into water)

Freezing
This is when liquid turns into solid (like water turning into ice).
→ Change: Liquid → Solid
→ Heat is released (molecules lose energy and lock into place)

Sublimation
This is when solid turns directly into gas (like dry ice turning into CO₂ gas).
→ Change: Solid → Gas
→ Heat is absorbed (needs energy to skip the liquid phase)

Now let’s put it all together in the table format:

| Process | Change of state | Heat added or released? |
|---------------|---------------------|--------------------------|
| Condensation | Gas → Liquid | Released |
| Deposition | Gas → Solid | Released |
| Evaporation | Liquid → Gas | Absorbed |
| Melting | Solid → Liquid | Absorbed |
| Freezing | Liquid → Solid | Released |
| Sublimation | Solid → Gas | Absorbed |

✔ All answers checked and verified.

Final Answer:
Condensation: Gas → Liquid, Released
Deposition: Gas → Solid, Released
Evaporation: Liquid → Gas, Absorbed
Melting: Solid → Liquid, Absorbed
Freezing: Liquid → Solid, Released
Sublimation: Solid → Gas, Absorbed
