The term "Water State" refers to the physical form that water takes, which can be classified into three main states: solid, liquid, and gas. In its solid state, water is known as ice, while in its liquid state, it is simply referred to as water. The gaseous state of water is called water vapor. These states are determined by temperature and pressure conditions. Water can change from one state to another through processes such as melting, freezing, evaporation, and condensation. For example, when ice is heated, it melts into liquid water, and when water is heated further, it evaporates into water vapor. These transitions are essential for various natural processes, including the water cycle, which involves evaporation from bodies of water, precipitation, and runoff.
