Energy source
Water is an important source of energy. The power of moving water is very high, so it is used to generate electricity. Hydroelectric power plants are built where water moves at high speeds, such as rivers. In addition, artificial structures, such as dams, which create water movement, can also be erected.
Water flowing from the upper level to the lower level through special turbine pipelines acquires greater speed. The stream of water then flows onto the blades of the hydraulic turbine and rotates them. This is how energy turns into mechanical energy. The generator connected to the turbine rotates and the mechanical energy becomes electrical. Transformers convert electricity into the required voltage. Electricity is sent through transmission lines to distribution stations.

Three states of water
Substances, depending on their freezing, melting and boiling temperatures, can be found in nature in three states of aggregation - solid , liquid and gaseous . Water freezes at 0°C and boils at 100°C.
In everyday life, we can encounter water in any of its three states, and its form is constantly changing. Liquid water evaporates and turns into a gaseous state - water vapor. It condenses and turns into liquid. At sub-zero temperatures, water freezes and turns into solid ice.
If we place table salt crystals in a vessel with water, we will be able to observe how the amount of solid substance gradually decreases. At the same time, water acquires new properties: it acquires a salty taste, density and freezing point change. The resulting liquid can no longer be called water, it is a solution. Intermolecular bonds arise between salt and water molecules, due to which salt molecules are detached from the surface of the crystal.

How much and where?
There is a total of 1390 million km 3 of water on the globe, most of it in the seas and oceans - 96.4%. On land, water is hidden in glaciers and permanent snow - about 1.86%. Antarctica, Greenland and many other islands in high latitudes are covered with eternal ice. In the mountains at high altitudes, mountain glaciers form. There is little water underground - only about 1.7% of the total volume, and land waters (rivers, lakes, swamps, reservoirs) account for approximately 0.02%. There is water in living organisms and in the atmosphere too. But there is little fresh water on the planet, which is so necessary for us to live - only 2.64%.

Water is the basis of life
All living things are 75% water. This is the most necessary element of living nature. Water constantly circulates between the seas, atmosphere and land, creating conditions in which life can exist and develop.
Water, at first glance the simplest chemical compound, is the basis of life on Earth. Water transports heat, dissolves and transports colossal masses of chemicals and elements, destroys and redistributes rocks, forms landforms, and even participates in the formation of minerals. In addition, water is involved in a number of meteorological phenomena, such as precipitation, fog, clouds. It is involved in the creation of currents, waves, movement of river beds and the formation of reservoirs. It is also a living environment for many organisms.
A person can live without water for only a few days. For the normal functioning of all organs, a person needs at least 1.5 liters of water per day. Water delivers nutrients to the body's cells and carries away waste products. In addition, water is involved in the processes of thermoregulation and human respiration.
Under the rays of the Sun, water evaporates from reservoirs and rises into the air. There, droplets of water collect in clouds and clouds and fall to the ground in the form of rain or snow, which turns into water. It is absorbed into the earth and again returns to the seas, rivers and lakes. And everything starts all over again. the water cycle occurs in nature.
