The water is shapeless and flows. Ice is hard and brittle. Both of these substances are composed of the same molecules. Explain why substances created from the same molecules have completely different properties?
All properties of a substance depend on the structure of its crystal lattice.
In the crystal lattice of ice, water molecules are combined into regular hexagons, so ice is hard and brittle. Liquid water does not have a rigid crystal lattice.
