What happens to water when it freezes?

Contracts
Disappears
Expands
Remains the same

The correct answer is: Expands

When water freezes, it turns into ice and expands. This is because the molecules in water are arranged in a lattice structure when they freeze, causing them to take up more space than they did when they were in liquid form. Option A, contracting, is incorrect because unlike most substances, water actually expands when it freezes. Option B, disappearing, is incorrect because while water may seem to "disappear" when it turns into ice, it is still a solid and has simply changed state. Option D, remaining the same, is also incorrect because water does undergo a physical change when it freezes, and it is no longer in its liquid form.
