The worksheet is about understanding how matter changes state when different conditions are applied. Let's solve each problem step by step:
1. Ice + Sun
-
Ice is solid water.
- When ice is exposed to the
Sun, it absorbs heat energy.
- The absorbed heat causes the ice to melt, changing its state from solid to liquid.
-
Result: Liquid water.
Answer: Water
2. Water + Fire
-
Water is in its liquid state.
- When water is exposed to
Fire, it absorbs heat energy.
- The absorbed heat causes the water to evaporate, changing its state from liquid to gas.
-
Result: Water vapor (gas).
Answer: Steam
3. Water + Cooler
-
Water is in its liquid state.
- When water is exposed to a
Cooler, it loses heat energy.
- The loss of heat causes the water to freeze, changing its state from liquid to solid.
-
Result: Ice.
Answer: Ice
4. Steam + Cloud
-
Steam is water in its gaseous state.
- When steam comes into contact with a
Cloud, it encounters cooler temperatures.
- The cooler temperatures cause the steam to condense, changing its state from gas to liquid.
-
Result: Liquid water.
Answer: Water
Final Answers:
1. Ice + Sun =
Water
2. Water + Fire =
Steam
3. Water + Cooler =
Ice
4. Steam + Cloud =
Water
Explanation:
-
Melting: Solid → Liquid (e.g., Ice → Water)
-
Evaporation: Liquid → Gas (e.g., Water → Steam)
-
Freezing: Liquid → Solid (e.g., Water → Ice)
-
Condensation: Gas → Liquid (e.g., Steam → Water)
Each process involves a change in temperature or energy that alters the state of matter.
Final Answer Boxed:
\[
\boxed{\text{Water, Steam, Ice, Water}}
\]
