Type a summary of the phases of water and how a substance changes from one to the other.

There are three phases of water that include solid water, liquid water and gas water. Water in solid phase has definite shape and size and molecules are closely packed for example: ice, water in liquid phase or  liquid water phase, molecules are close together but can move as per the shape of container, for example: juice; and gas water phase is the phase in which molecules are far from each other.

Same as matter, the phases of water also changes as per the temperature and pressure of the ecosystem changes. When temperature increases, Solid water changes to liquid water and the process called melting and  liquid water convert into gas water and the process called vaporization. When temperature decreases, liquid water convert into solid water with the process freezing and gas water convert into liquid water through condensation.
