Answer:
- Liquid water and ice consists of aggregates of varying number of water molecules held together by hydrogen bonds.
- Due to the hydrogen bonding, ice has an open cage-like structure having a number of vacant spaces.
- When ice melts, some of the hydrogen bonds are broken and the water molecules go in between the vacant spaces in the structure. As a result, the structure of liquid water is less open than structure of ice.
- Therefore, the density of ice is less than that of water and consequently ice floats on water.

Answer:
Like most things that float, ice floats because it is less dense than liquid water. Ice is about 9% less dense. When ice forms, it takes up about 9% more space than it did as a liquid. Thus, a 1 liter container of ice weighs less than a 1 liter container of liquid water, and the lighter material floats to the top......
