The density of water and ice are different, which means that a cubic foot of water will weigh more than a cubic foot of solid ice at zero degrees Celsius.
The density of water is approximately 62.43 pounds per cubic foot (lb/ft³) at 4 degrees Celsius, which is the temperature at which water has its maximum density. However, at zero degrees Celsius, water has a slightly lower density, but the difference is negligible for practical purposes.
On the other hand, the density of solid ice at zero degrees Celsius is approximately 57.3 pounds per cubic foot (lb/ft³). When water freezes and transforms into ice, it expands and becomes less dense.
Therefore, a cubic foot of water will weigh more than a cubic foot of solid ice at zero degrees Celsius.
