How do people use water properties? Water properties and conditions

Many people know that the water gave birth to life on planet Earth. It is this substance that scientists are looking for on Mars to prove that there is also fauna and flora here. Man today can not imagine existence without water. All thanks to the miraculous properties of this material.

Water in nature

Water is a liquid without odor and taste. This natural material has almost no color. In deep layers, water can have a bluish tinge. This is one of the most common substances in nature, without which no creature can do. Surprisingly, the hydrosphere occupies more than 70% of the entire biosphere.

Water is a mineral by which industry is organized today, houses are built, and there are also power plants. Scientists have found that water is a remarkable solvent. Therefore, it is impossible to find an ideally pure substance in nature. More often there is a liquid with various impurities of organic and inorganic materials. There are a lot of varieties of water. All of them have found their application in human life. How people use water properties will be described below.

Properties of water

A natural mineral can exist in three forms - in a solid, liquid and vapor state. The most common is the liquid. The properties of water depend directly on its state. When frozen, the substance loses its density and rises to the surface. Thanks to this, water under ice always keeps its temperature. Even if the air temperature dropped below 40 degrees Celsius, the underwater living organisms will continue to exist.

Considering the properties and conditions of water, one can not help recalling the surface tension. This figure is significantly higher than that of any other liquid. It is because of this that raindrops can form. Surface tension is one of the main indicators that affect the water cycle in nature. We can personally observe the properties of water. Experiments can be conducted at home. It's very interesting and exciting. All that needs to be done is to draw water into the cup to the edge and throw in turn coins or other small items in it. You can notice that the water does not pour out immediately beyond the edges of the container, but forms a small hill. This is due to the force of surface tension.

Boiling temperature

All liquids that exist in nature have their boiling point. Water is not an exception. This material has the highest boiling point. These thermophysical properties of water are of great importance in the existence of all living things. The liquid can boil at a temperature of about 100 degrees Celsius. This indicator may vary slightly depending on what impurities are added to the water. It is the boiling point that directly affects the evaporation process. The higher this index, the less water loss in nature.

The thermophysical properties of water are also widely used in everyday life. During the boiling in water, various pathogens die. Due to this process, it is possible to purify the liquid of various impurities. Boiled water can be eaten without hindrance. This liquid is also used for the treatment of medical instruments and wounds.

Water in heat power industry

People have been searching for natural sources of energy for many centuries. Such a source can become ordinary water. It is no coincidence that this substance is widely used today in heat power engineering. This material plays just two roles - the coolant and the working fluid. In order to produce one megawatt of electricity, it is necessary to use about 30 cubic meters of water per second. The liquid is also used to cool the turbine of the power unit's condenser. It turns out that without water it would be impossible to establish access to electricity, and many buildings would simply not be heated.

In the second half of the 20th century, 50% of electricity was generated by hydroelectric power stations. This allowed people to organize a normal way of life, and the ecological situation remained at the level. The use of water by a person is not exhausted, if he does everything right. The presence of a large number of cars, exhausts from various factories and plants lead to the fact that the amount of clean water decreases. Today, much less electricity is produced by water.

Chemistry and water

If we consider the chemical properties of water, then first of all comes to mind the possibility of liquid dissolving other substances. It is water that is the main reagent in many chemical reactions. This property is widely used in everyday life, as well as production. Water is a special vehicle that allows you to move chemical reaction products from one technological device to another. In the environment, liquid wastes also come in the form of suspensions and solutions. The chemical industry simply could not exist without water.

In everyday life it is also possible to easily trace the properties of water as a solvent. It should be noted that the ability to dissolve individual substances depends on the temperature of the water. Many noticed that fatware can easily be washed in warm water. But the low temperature does not give such a possibility. In everyday life, you can also notice how such well-known products as salt, sugar and soda are dissolved in water. Tea is an aqueous solution that is not only useful, but also delicious.

Water in medicine

It is very common for people to use water for medical purposes. Here, water often also acts as a solvent. It can also be used as a medicine and an auxiliary substance for hygiene and sanitation. In recent years, the level of medical care has significantly increased. The number of the world's population is also increasing every year. This leads to the fact that the need for water consumption for medical purposes is increasing.

To treat many ailments, the properties of liquid water are used. Of course, the substance is not used in its pure form. With the participation of water, various drugs, solutions and suspensions are made. And the boiling point of the liquid is used to process medical instruments and shapes.

Many medications are effective only if you consume enough fluids. This can always be read in the instructions for use of the drug. Water plays the role of a vehicle, allowing the medicine to reach the desired organ more quickly.

Water in agriculture

It is impossible to imagine agriculture without liquid. How do people use the properties of water in this area? The substance helps deliver useful trace elements and minerals to animal and plant cells. Water is a mandatory participant in various metabolic reactions, as well as the process of photosynthesis. In addition, the temperature of animals and plants is regulated by means of a liquid. Few people know that the volumes of water that are used for watering plants, as well as the maintenance of livestock, are not inferior to industrial volumes.

In order to qualitatively grow vegetables and fruits, it is necessary to organize watering competently. In many cases, specialists can not do without. Only a professional can adjust the work in such a way that water is delivered to each plant on the site. To hope only for the rain is to ruin the land.

How people use water properties in cosmetology

No cosmetic means can be manufactured without water. But in this sphere the special thermal water, which has the properties of rejuvenation and skin regeneration, is most often used. The composition of the liquid from thermal springs includes trace elements and minerals that can restore the health of the skin and hair of any type.

Pure water is also used in cosmetology as a solvent. With the help of liquid, various creams, masks and shampoos are prepared. Cosmetics are often also prepared at home. Before cooking, you need to study the properties of water briefly. It is necessary to strictly follow the prescription, so that the cosmetics turned out to be really qualitative and useful.

Water at home

How do people use the properties of water at home? Here the liquid acts more often as a food product, and also means of hygiene and sanitation. Water can also act as a participant in various chemical reactions that occur when cooking. Heat power properties of the liquid are widely used . For example, in food, most often boiled water is used.

Heat supply for apartment buildings is also organized thanks to water. The liquid, heating to the right temperature, can maintain the heat in the houses for a long time.

Even in elementary school, children begin to study the properties of water. 2nd class is the time when children begin to get acquainted with one of the important substances in nature. The teacher's task is to teach the child to save water resources in order to prolong life on the planet.
