Let's solve the "States of Matter Cut & Paste" worksheet step by step.
The goal is to understand what happens when heat or cold is added to a substance in a given state, and to fill in the
new state and an
example for each change.
---
1. Solid + Heat → ?
-
State: Solid (shown as tightly packed dots)
-
Add: Heat
-
What happens? When you add heat to a solid, it melts into a liquid.
-
New State: Liquid
-
Example: Ice melting into water
✔ Answer:
- New State:
Liquid
- Example:
Ice melting into water
---
2. Liquid + Heat → ?
-
State: Liquid (shown as loosely packed dots)
-
Add: Heat
-
What happens? When you add heat to a liquid, it evaporates into a gas.
-
New State: Gas
-
Example: Water boiling into steam
✔ Answer:
- New State:
Gas
- Example:
Water boiling into steam
---
3. Gas + Cold → ?
-
State: Gas (shown as widely spaced dots)
-
Add: Cold (cooling)
-
What happens? When you cool a gas, it condenses into a liquid.
-
New State: Liquid
-
Example: Steam condensing on a cold mirror
✔ Answer:
- New State:
Liquid
- Example:
Steam turning into water droplets on a cold surface
---
4. Liquid + Cold → ?
-
State: Liquid (same as above)
-
Add: Cold
-
What happens? When you cool a liquid, it freezes into a solid.
-
New State: Solid
-
Example: Water freezing into ice
✔ Answer:
- New State:
Solid
- Example:
Water freezing into ice
---
✔ Final Completed Table:
| STATE | ADD | NEW STATE | EXAMPLE |
|-------|-----|-----------|---------|
| SOLID | + HEAT |
LIQUID |
Ice melting into water |
| LIQUID | + HEAT |
GAS |
Water boiling into steam |
| GAS | + COLD |
LIQUID |
Steam condensing on a cold surface |
| LIQUID | + COLD |
SOLID |
Water freezing into ice |

🔍 Explanation:
This worksheet teaches
phase changes due to temperature changes:
-
Melting: Solid → Liquid (add heat)
-
Evaporation: Liquid → Gas (add heat)
-
Condensation: Gas → Liquid (remove heat / add cold)
-
Freezing: Liquid → Solid (remove heat / add cold)
These are fundamental concepts in the
states of matter.
