Recall the relationship between density, mass, and volume, which is given by the formula: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Since the problem states equal masses of liquid water and ice, compare their densities to understand their relative volumes.
Know that the density of liquid water is approximately 1.00 g/cm³, while the density of ice is about 0.92 g/cm³, meaning ice is less dense than liquid water.
Because density is inversely proportional to volume for a fixed mass, the substance with lower density (ice) will occupy a larger volume than the substance with higher density (liquid water).
Therefore, for equal masses, ice occupies more volume than liquid water due to its lower density.
