Water is everywhere. This is the most common in nature substance. A large part of the surface of the planet is occupied by seas and oceans, once, according to research scientists, from it walked on land all land creatures.
Water – an amazing substance that has no analogues in nature. This substance, which is able to change radically under the influence of the ambient temperature.
The Three States of water – ice, liquid, gas – are called aggregate. They are at first glance so different, and you may think that it is different materials. However, the fallen morning snow, rain, and passing clouds over their heads – types of the same substance, but with different physical properties, and qualitatively different from each other.
The Three States of water is very important for our planet, as they provide the cycle. With water surfaces rivers, seas and oceans, the liquid evaporates under the influence of sunlight, is transformed into a gaseous state i.e. steam. He rises up, turning into clouds. Since the temperatures are lower, water droplets are formed (it turns back into a liquid). From the clouds as rain water falls on the earth, fills the rivers and Oceans.
On the question, what is water, many people did not hesitate to answer - liquid! Will not quite right. Of course, we are accustomed to see water in nature mostly in a liquid state. However, it has three forms: liquid, solid (snow, ice, hail) and gas (steam, cloud). You will examine each option in detail.

If you compare the three States of water, in liquid form it is more common with fairly wide spectrum of temperatures (from 0 to 100). In rivers, lakes, seas, oceans, it has a liquid substance. Dew, rain – precipitations in the form of liquid. It has no shape, taste and smell – all of this water is attached to the external influence. For example, the liquid takes on the shape of the dishes, where we poured, takes the smell and taste of additives (the same chlorine in the water). The liquid form of water is yielding but has great power. As the saying goes, water hollows out a stone. And the water creates caves and destroys the rocks, changing the planetary landscape.
If you take all three States of water, liquid is for man, and for all life on Earth is of paramount importance. H2O is widely used in households for hygiene and sanitation: everywhere there is a demand for water in liquid form. But each person per day need to consume quite a large amount (2 liters) to replenish the water balance. Scientists have proved that without food with some training the person can manage up to 40 days, but without water and wouldn't last a week. Comes dehydration at the cellular level, and then death.
Any substance in the world consists of small particles that are in motion. When temperatures drop to minus water particles begin to move slower and the liquid acquires a solid structure. Empirically you can verify: liquid (water) in the transition to solid state not only turns to ice, but also changes in the volume – is expanding (almost all items using the same cooling, on the contrary, reduced in size).
If the glass bottle with water to freeze, it will burst. Ice on the ponds and mighty icebergs, icicles on the roof, snow, hail – all of this solid state of water. The nature and economic life of the people ice is important, performing a protective, sanitary, cooling function. For example, cooling medicines, or food products.
But the ice in nature can be a disaster. Hail and icing of wires leading to the cliffs, sleet, leading to injuries, the freezing of the soil and snow avalanches – all effects of the solid state of water.
Considering the 3 States of water, it is impossible not to pay attention to her third incarnation – water vapor. Heat the water to 100 degrees, will receive its transition into the gas state. In nature this form is found in the form of various kinds of clouds, fogs, fumes, humidity increases. But in the atmosphere of our planet are constantly fine water particles.
The Gaseous state of water by artificial means, has played a huge role in the development of scientific and technical progress and in the life of all mankind. Steam machines in the last century, was used widely (not to mention the 19th century) for generating energy, whereby the units could dislodge. For example, the engine and the vehicle runs using the power of steam.
All the three States of water in nature to humankind are of great value. And the transition from one form to another performs the function of deep cleansing of the environment. As a result of the circulation of huge masses of liquid self-cleaning and bring benefits to the person. In this regard, there is a clear need to protect water resources, keep them clean and don't pollute the water with waste products of human and industrial emissions.
