Introduce the strength of the skin to the skin Introduce the state of gas in the name of steam. Units are defined as freezing temperatures (formerly and now deficient) from the triple point of water, 273.16 degrees Celsius (0.01 degrees Fahrenheit) and 611.2 degrees Celsius. The water shows some of the poorer behavior, as well as in the formation of conditions such as the solid volume, the non-crystalline state, and the solid state of the water.

At the highest degrees of heat from 647 cliffs and a large mass of 22,064 megabytes.

Water is the measure of the amount of water in the air column.

The dipolar nature of the water molecule

An important feature of water molecules is their polar nature. The water molecule forms an angle, with hydrogen atoms at the end and oxygen at the top. Because oxygen has a higher electrical concentration than hydrogen, there is a partial negative charge on the side of the molecule with the oxygen atom. To compensate for this difference, the molecule is called a dipole. The difference in charge causes water molecules to be attracted to each other (relatively positive regions are attracted to relatively negative regions) and to other polar molecules. This attraction is known as hydrogen bonding. Water Molecule

This is due to the relatively weak gravity (compared to the quantal bonds in the water molecule itself) resulting in physical properties such as a relatively high boiling point because most thermal energy is required to break the hydrogen bonds between the molecules. For example, the periodic table contains the element sulfur below oxygen, and its equivalent compound, hydrogen sulfide (H2S), does not contain hydrogen bonds, and although it has twice the molecular weight of water, it has room temperature. But there is a gas. The extra links between the water molecules also give liquid water a very special heat capacity.

Hydrogen bonding also gives water molecules an unusual treatment when frozen. Just like other substances, as the temperature decreases, so does the liquid. However, unlike many other substances, when cooled to an almost freezing point, the presence of hydrogen bonds means that the molecules actually formless dense structures when rearranged to reduce their energy. Are: therefore solid shape, will float in ice, water. In other words, water expands when it is strong (contracts when most other substances are strong). Liquid water reaches its high density at a temperature of 4 ° C, which is an interesting result of winter aquatic life. Cooling water on the surface decreases and sinks, creating thermal currents that cool the entire body of water, but when the lake water temperature reaches 4 ° C, the surface water decreases. Becomes thicker, cools more, and so on. A layer of surface eventually forms ice. Since the cold water side is obstructed due to the change in density downwards, in winter a large part of the frozen water will liquefy a large part of the water at 4 degrees Celsius above the ice surface, allowing the fish to survive. Will This fine bread is an example of the physical characteristics that support life on earth that are used as evidence of human principle.
