Many people know that thanks to water, life was born on planet Earth. It is this substance that scientists on Mars are looking for to prove that fauna and flora are also present here. Man today cannot imagine existence without water. All thanks to the miraculous properties of this material.
Water in nature
Water is an odorless and tasteless liquid. This natural material has practically no color either. In deep layers, water may have a bluish tint. 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 the mineral with which industry is organized today, houses are built, and there are also power plants. Scientists have found that water is a wonderful solvent. Therefore, it
is impossible to find a perfectly
pure substance in nature. More common is liquid with various impurities of organic and inorganic materials. There are a huge number of varieties of water. All of them have found their application in human life. How people use the properties of water will be described below.
Water properties
A natural mineral can exist in three forms - in a solid, liquid, and vapor state. The most common is precisely the liquid. The properties of water directly depend on its condition. When freezing, the substance loses its density and rises to the surface. Thanks to this, water under the ice always maintains its temperature. Even if the air temperature drops below 40 degrees Celsius, underwater living organisms will continue to exist.
Considering the properties and conditions of water, one can not help but recall surface tension. This indicator is significantly higher than that of any other fluid. 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 carried out at home. It is very interesting and exciting. All you need to do is to draw water into a glass to the edge and toss coins or other small objects into it alternately. You may notice that the water does not pour out immediately over the edges of the tank, but forms a small hill. This is due to the surface tension force.
Boiling temperature
All liquids that exist in nature have their boiling point. Water is no 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 processes. The higher this indicator, the less water loss in nature.
The thermophysical properties of water are also widely used in everyday life. During boiling in water, various pathogens die. Thanks to this process, it is possible to clean the liquid from various impurities. Boiled water can be freely consumed. Such a liquid is also used to treat medical instruments and wounds.
Water in the power system
For centuries, people have been searching for natural sources of energy. This source can be ordinary water. It is no coincidence that this substance is widely used today in the power system. This material plays two roles at once - 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 condenser of the power unit. 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 precisely by hydroelectric power plants. This allowed people to organize their everyday life, and the environmental 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 plants and factories lead to the fact that the amount of clean water is reduced. Today, much less electricity is generated thanks to water.
Chemistry and water
If we consider the chemical properties of water, it first comes to mind the ability of a liquid to dissolve 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 in production. Water is a special vehicle that allows you to move the products of a chemical reaction from one technological device to another. Liquid wastes also enter the environment in the form of suspensions and solutions. The chemical industry simply could not exist without water.
In everyday life, you can also easily track the properties of water as a solvent. It is worth noting that the ability to dissolve individual substances depends on the temperature of the water. Many noticed that greasy dishes can easily be washed in warm water. But low temperature does not give such an opportunity. In everyday life, you can also notice how such well-known products as salt, sugar and soda dissolve in water. Tea is an aqueous solution that is not only useful, but also tasty.
Water in medicine
The use of water by humans for medical purposes is very common. Here, water most often also acts as a solvent. It can also be used as a medicine and excipient for hygiene and sanitation. In recent years, the level of medical care has grown significantly. The population of the planet is also increasing every year. This leads to an increase in the need for water consumption for medical purposes.
For the treatment of 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 medicines, solutions and suspensions are made. And the boiling point of a liquid is used to process medical instruments and molds.
Many medicines work effectively only when drinking enough fluid. You can always read about this in the instructions for use of the medicine. Water plays the role of a vehicle, allowing the medication to quickly reach the desired organ.
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 to deliver useful trace elements and minerals to animal and plant cells. Water is an obligatory participant in various metabolic reactions, as well as in the process of photosynthesis. In addition, the temperature of animals and plants is regulated with the help of a liquid. Few people know that the volumes of water used to irrigate plants, as well as livestock, are not inferior to industrial volumes.
In order to properly grow vegetables and fruits, it is necessary to properly organize watering. In many cases, not without specialists. Only a professional can arrange work so that water is delivered to each plant on the site. Hoping only for rain means ruining the land.
How people use the properties of water in cosmetology
No cosmetic product can be made without water. But in this area, special thermal water is most often used , which has the properties of rejuvenation and skin restoration. 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 liquids, various creams, masks and shampoos are prepared. Cosmetics are often prepared also at home. Before preparing products, it is necessary to study the properties of water briefly. It is necessary to strictly follow the recipe so that the cosmetics turn out to be really high-quality and useful.
Water in the home
How do people use the properties of water at home? Here, the liquid acts most often as a food product, as well as a means of hygiene and sanitation. Water can also be a participant in various chemical reactions that occur during cooking. The heat and power properties of the fluid are widely used . For example, boiled water is most often used in food.
The heat supply of apartment buildings is also provided by water. The liquid, heated to the desired temperature, can maintain heat in homes for a long time.
Even in elementary school, kids begin to study the properties of water. Grade 2 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 in order to prolong life on the planet.
