    Question: By approximately what percentage does water expand in volume when it freezes?

    Options:

    4%
    9%
    14%
    90%

    ✅Explanation:
    When water freezes, its volume increases by approximately 9%. This is due to the molecular structure of ice, where the molecules are arranged in a hexagonal lattice that is less dense than liquid water, causing ice to occupy more space and float on water.
