Answer

Brief Explanations:

Water has an unusual property. When it freezes to form ice, it expands. Since density is mass per unit volume ($\rho=\frac{m}{V}$), with mass remaining constant and volume increasing upon freezing, the density of ice is less than that of liquid water. Objects with lower density than the fluid they are in will float.

Answer:

Water expands and becomes less dense when it freezes.
