Understanding the Concepts
* Density: Density is a measure of how much mass is contained in a given volume. The density of water is about 1 g/mL, while the density of ice is about 0.92 g/mL. This means ice is less dense than water.
* Expansion: When water freezes, it expands because the molecules arrange themselves into a more open, crystalline structure. This expansion is why ice floats.
Calculations
1. Mass of water: Since the density of water is 1 g/mL, 325 mL of water has a mass of 325 g.
2. Volume of ice: We know the mass of ice is still 325 g. To find the volume, we use the density of ice:
Volume = Mass / Density = 325 g / 0.92 g/mL ≈ 353.26 mL
Result
The volume of the water will increase from 325 mL to approximately 353.26 mL when it freezes.
