Many people know that, thanks to the water life began on Earth.It is this substance on Mars, scientists are seeking to prove that there are fauna and flora.Man today can not imagine existence without water.All thanks to the miraculous properties of this material.
water in nature
Water is a liquid with no odor or taste.The colors of this natural material is also almost does not matter.In the deeper layers of water can have a bluish tint.This is one of the most common substances in nature, without which it can not do any one thing.Surprisingly, hydrosphere takes more than 70% of the biosphere.
Water - a mineral with which the industry is organized today, houses are being built, as well as existing plants.Scientists have found that water is an excellent solvent.Therefore found in nature can not perfectly pure substance.More common fluid with various impurities of organic and inorganic materials.There are many varieties of water.All of them have been applied in human life.As people use the properties of water, will be described below.
Water Properties
natural mineral can exist in three forms - solid, liquid and vapor.The most common is it liquid.Properties of water depends on its condition.When freezing the substance loses its density and rises to the surface.Due to this the water under the ice always keeps its temperature.Even if the air temperature is below 40 degrees Celsius, underwater organisms continue to exist.
Considering the characteristics and condition of the water, one can not forget about the surface tension.This is significantly higher than any other liquid.Precisely because of this it can form raindrops.Surface tension is one of the key indicators that affect the water cycle.We can personally observe the properties of water.Experiments can be performed at home.This is a very interesting and exciting.All you have to do is type in a glass of water up to the edge and throw it in turn a coin or other small items.It can be seen that the water does not come out right behind the edge of the container and forms a small hill.This is due to the force of surface tension.
Boiling
All liquids which are found in nature have its boiling point.Is no exception and water.This material has a high boiling point.These thermal properties of water are vital to the existence of all living things.The liquid may boil at about 100 degrees Celsius.This figure may vary slightly depending on which impurities are added to the water.That boiling temperature directly affects the process of evaporation.The higher the score, the less water loss in nature.
Thermal properties of water are also widely used in everyday life.While boiling in water die various pathogens.Through this process, the liquid can be purified from various impurities.Boiled water can be freely eaten.Such a liquid is also used for treatment of wounds, and medical instruments.
water in power
People have for centuries looking for natural sources of energy.Such a source can be plain water.It is no coincidence this material is now widely used in thermal power generation.This material is playing two roles at once - coolant and working medium.In order to produce one megawatt of electric power is necessary to use about 30 cubic meters of water per second.Fluid is also used to cool the turbine condenser unit.It turns out that without water it would be impossible to establish, and access to electricity, and many buildings have simply not heated.
In the second half of the XX century 50% of electricity is generated by hydroelectric power plants it.This allowed people to organize normal life and the environmental situation remained level.The use of water is not issyakaemo man, if he does everything right.The large number of automobiles, exhaust from various factories leads to the fact that the amount of pure water is reduced.Today, it is much less electricity is generated through water.
Chemistry and water
If we consider the chemical properties of water, the first thing comes to mind is the possibility of liquid to dissolve other substances.That water is the main reactant in many chemical reactions.This property is widely used in everyday life, as well as production.Water - a special vehicle, which can move the chemical reaction products from one unit process to another.The environmental waste liquid fall also as suspensions and solutions.Chemical industry simply could not exist without water.
At home you can also easily keep track of the properties of water as a solvent.It should be noted that the ability to dissolve the individual substances depends on water temperature.Many noticed that greasy dishes easily able to wash in warm water.But the low temperature of such a possibility does not.In everyday life it can also be seen as a water soluble such well-known products, such as salt, sugar and baking soda.Tea - is an aqueous solution that is not only useful but also delicious.
Water in medicine
very common use of water for human medical purposes.Here, the water often also acts as a solvent.It can also be used as a drug and an excipient for hygiene and sanitation.In recent years, significantly increased the level of medical care.The number of the world's population is also increasing every year.This leads to the fact that water consumption increases the need for medical purposes.
to treat many ailments, use the properties of liquid water.Of course, the substance is not used in pure form.With the participation of water produced various medications, solutions and suspensions.A boiling point of the liquid used for treatment of medical instruments and shapes.
Many drugs are effective only in the use of a sufficient amount of liquid.This can always be found in the instructions for use of the drug.Water acts as a vehicle, allowing the medicament will reach the desired organ.
water in agriculture
impossible to imagine agriculture without liquid.How people use the properties of water in this area?The substance helps deliver useful trace elements and minerals to the cells of animals and plants.Water is a necessary party to various metabolic reactions, as well as the process of photosynthesis.Furthermore, the liquid temperature is controlled using animals and plants.Few people know that the volume of water used for irrigation and livestock, are not inferior to industrial scale.
To grow high quality vegetables and fruits must be well-organized irrigation.In many cases, can not do without specialists.Only a professional can organize the work so that the water delivered to each plant at the site.Rely only on the rain - it means ruin land.
How people use the properties of water in cosmetology
None cosmetology tool can not be manufactured without water.But in this area it is most often used special thermal water, which has the properties of rejuvenation and skin repair.The composition of the thermal fluid sources comprises trace elements and minerals that can restore healthy skin and hair types.
Pure water is also used in cosmetics as a solvent.Using liquid prepare various creams, masks and shampoos.Cosmetics are often also preparing at home.Before preparing the product is necessary to study the properties of the water briefly.It is necessary to strictly follow the recipe to get a really high-quality cosmetics and useful.
water in the home
How people use the properties of water at home?Here, the liquid acts mostly as food, as well as hygiene and sanitation.Water can also act as a member of various chemical reactions that occur during cooking.Widely used thermal power fluid properties.For example, in the diet is used most often boiled water.
Heat supply of houses is also organized through the water.The liquid is heated to the desired temperature can be for a long time to maintain the heat in their homes.
early as elementary school kids are beginning to explore the properties of water.Class 2 - a time when children begin to get acquainted with one of the most important substances in nature.The task of the teacher - to teach children to save water resources, to extend the life of the planet.
