Step-by-Step Solution
Ice floats on water because it has a cage-like structure formed by hydrogen bonding, which creates empty spaces between its molecules. Due to these vacant spaces, the volume of ice increases, making its density lower than that of liquid water. Objects with lower density than the liquid they are placed in float on its surface.
