Solid Molecular Structure

Ice is an example of a solid molecular structure, where the water molecules are arranged in a specific pattern with a fixed shape and volume. The molecules in ice are held together by intermolecular forces, which create a rigid lattice structure. The lattice structure of ice also makes it less dense than liquid water.

Change of State

A change of state is a physical change in which matter goes from one state (solid, liquid, or gas) to another. Ice is a good example of a change of state, as it can melt into liquid water when heated and evaporate into water vapor when exposed to heat. These changes are reversible and depend on the temperature and pressure of the surroundings.
