I need to work through this worksheet about changing states of matter. Let me analyze what's being asked.
The worksheet shows the three states of matter (ice, water, steam) and asks students to fill in blanks describing how water changes from one form to another using words from a word bank.
Looking at the diagram:
- There are arrows showing transitions between ice → water → steam and back
- Each transition has two sentences with blanks to fill
- The word bank likely contains: heat, cool, melts, freezes, condenses, evaporates, 0°C, 100°C
Let me work through each transition:
Ice to Water (melting):
- If you ___ water to a temperature of ___, it ___ to form water.
- This should be: If you HEAT ice to a temperature of 0°C, it MELTS to form water.
Water to Ice (freezing):
- If you ___ water to a temperature of ___, it ___ to form ice.
- This should be: If you COOL water to a temperature of 0°C, it FREEZES to form ice.
Water to Steam (evaporation/boiling):
- If you ___ water to a temperature of ___, it ___ to form steam.
- This should be: If you HEAT water to a temperature of 100°C, it EVAPORATES (or boils) to form steam.
Steam to Water (condensation):
- If you ___ steam to a temperature of ___, it ___ to form water.
- This should be: If you COOL steam to a temperature of 100°C, it CONDENSES to form water.
Wait, let me reconsider the temperatures more carefully:
- Melting/freezing point of water is 0°C
- Boiling/condensation point of water is 100°C
So the answers should be:
Top left (Ice → Water):
If you HEAT ice to a temperature of 0°C, it MELTS to form water.
Top right (Water → Ice):
If you COOL water to a temperature of 0°C, it FREEZES to form ice.
Bottom left (Water → Steam):
If you HEAT water to a temperature of 100°C, it EVAPORATES to form steam.
Bottom right (Steam → Water):
If you COOL steam to a temperature of 100°C, it CONDENSES to form water.
Final Answer:
Ice to Water (top left box):
If you
heat ice to a temperature of
0°C, it
melts to form water.
Water to Ice (top right box):
If you
cool water to a temperature of
0°C, it
freezes to form ice.
Water to Steam (bottom left box):
If you
heat water to a temperature of
100°C, it
evaporates to form steam.
Steam to Water (bottom right box):
If you
cool steam to a temperature of
100°C, it
condenses to form water.
