Checking the Water Level After Floating Ice Melts
Base your answers on the information provided and your knowledge of chemistry. Use the 2025 Chemistry Reference Tables as needed.
A display floats a 10.0 g piece of pure ice in water. The ice has a total volume of 10.9 mL. In the model, floating ice displaces its own mass of water. Liquid water has a density of 1.00 g/mL. The ice melts completely without water leaving the container.
| Quantity | Reading |
|---|---|
| Ice mass | 10.0 g |
| Full ice volume | 10.9 mL |
| Volume of displaced water while it floats | 10.0 mL |
Question 1
Which reading describes how much space the floating ice takes up below the water surface?
- 10.9 mL total ice volume
- 10.0 mL displaced water volume
- 10.0 g ice mass
- The difference between the full volume and mass
Question 2
Calculate the volume of the liquid made when the ice melts. Compare it with the previous submerged volume.
Write your answer and work on the printable worksheet, or answer online.
Question 3
A student predicts a lower water level because the full volume of the ice exceeds the melt volume. Explain why the displaced volume gives the appropriate comparison.
Write your answer and work on the printable worksheet, or answer online.
The particle display represents ice as a more open arrangement of water molecules held by attractions between molecules. The molecules themselves stay intact during melting.
Question 4
Use the particle model to explain why the full ice volume can exceed the melt volume even though the mass stays fixed.
