The water available in a variety of forms. First, commonly known as a liquid, secondly, as a solid form of ice, and thirdly as a gas-steam. But in addition to the standard forms that water takes, it also has amazing properties as well. These properties are usually referred to as anomalous properties. Some of these anomalous properties belong to different noise levels at different temperatures and surface tension.
Volume of water at different temperatures
Have you ever wondered whyLines, freeze water when the outbreak, or why ice floats in a river instead of falling? It 'easy, due to the fact that the volume of water varies depending on the temperature. For example, the volume of water by about 9% increase in the freezing point. As the water molecules become even colder, to go further. Therefore, the water in the pipes can burst, as well as why ice floats on liquid. At the other end of the spectrum, the molecules of water should boil90 degrees Celsius, but because of the hydrogen bonds in the molecule, water boils at a higher temperature-100 degrees Celsius, to be exact.
Surface tension
Surface tension is another anomalous properties of water. It can be shown easily if an insect falls into a pond or pool. Water can be a very closed and elastic substance. This is due to the fact that water molecules are more attracted to other water molecules next to him. It should be noted however, thatThe surface tension is only present on the surface of the reason that the water beneath the surface of the pool or pond is low. Load zero means that no net force on the molecule, but water works only on the surface with different forces laterally and downwards. This is what creates a membrane tension and surface tension.
Pure Water
Pure water is not so clear, in fact it is almost impossible to create with only pure water molecules of H2O.In all cases, the pure water usually means that it is distilled or deionized, but there are still many gases dissolved silica and sometimes even within the molecules.
Drinking water
In contrast to pure water, our drinking water is usually full of many different substances, including feelings such as calcium, magnesium, iron, and even atmospheric gases. It should be noted that drinking water can be positive or negative charge, but these ions are usually symmetricalfrom the negative ion carbonate / bicarbonate, chloride and sulfate, and occasionally.
Because the water can easily dissolve most substances, if you're in an area where the water comes into contact with live toxic agents, this can affect your water to a certain extent. The EPA (Environmental Protection Agency) has limits on the amount of contaminants in drinking water and drinking water is a test of regular permits.
If you believe that the only way toAvoid contamination by potentially harmful substances is water directly from rain or snow, you should know that these forms of water pollution can also be drunk mainly due to dust particles in contact with the water in the atmosphere.
