The view first developed in the 1950's that water is a collection of flickering clusters of varying sizes (right) has gradually been abandoned as being unable to account for many of the observed properties of the liquid. Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions because your body loses water through breathing,. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge this allows the water molecule to become attracted to many other different types of molecules. Water can moderate temperature because of the two properties: high-specific heat and the high heat of vaporization high-specific heat is the amount of energy that is absorbed or lost by one gram of a substance to change the temperature by 1 degree celsius. describe how hydrogen bonding occurs between water molecules, and relate this and other properties of water, to the roles of water in living organismswater is a very small molecule, consisting of two hydrogen atoms covalently bonded to an oxygen atom.
Specific heat maintain a livable environment on earth because water has a high specific heat and water covers most of earth it keeps temp fluctuations on land and water within limits that permit life. Functions of water in the body the human body is anywhere from 55% to 78% water depending on body size a rule of thumb, 2/3 of body is consists of water, and it is the main component of human body. All of the water a person needs does not have to come from drinking liquids, as some of this water is contained in the food we eat water serves a number of essential functions to keep us all going: a vital nutrient to the life of every cell, acts first as a building material.
Water has many properties and functions one of them is its ability to be a solvent a known face is that water is called the universal solvent because it can dissolve many substances. Water has important roles and functions in chemistry, biochemistry and biology due to its diverse properties (that is, the way it behaves) chemicals can be described in terms of two types of properties. Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of earth's streams, lakes, and oceans, and the fluids of most living organisms. This attraction, hydrogen bonding, explains many of the properties of water, such as its solvent properties  although hydrogen bonding is a relatively weak attraction compared to the covalent bonds within the water molecule itself, it is responsible for a number of water's physical properties.
Another important property is that many compounds dissolve and transfer a proton (a hydrogen nucleus) to a water molecule the result is an acidic solution with ph 7 compounds that release a proton in this way are called acids. Functions of water in the body nearly all of the major systems in your body depend on water. Water's solvency is why the water that we use is rarely pure it usually has several minerals dissolved in it the presence of these minerals is the difference between hard water and soft water hard water usually contains a lot of calcium and magnesium, but may also contain metals. Water has several properties that make it unique amongst compounds and make it possible for all forms of known life to function it is the only natural substance found in all three physical states at the temperatures that naturally occur on earth. The unique physical properties of water, the chemistry of water, the density of water are anomalies that strongly suggest that an infinite intelligence created water if only one of these functions were missing, there would be no life on earth.
Water has many unusual properties because of its polar covalent bonds oxygen has a larger electronegativity than hydrogen, so the electron pairs are pulled in closer to the oxygen atom, giving it a partial negative charge. Water is essential for cells to function properly: it enters into the composition of the cells chemical and metabolic reactions by enabling hydrolysis reactions, water participates in the biochemical breakdown of what we eat (proteins, lipids and carbohydrates. Many regard water (h 2 o) as a rather uninteresting substance because it is transparent, odorless, tasteless and ubiquitous it is the simplest compound of the two most common reactive elements in the universe, consisting of just two hydrogen atoms attached to a single oxygen atom.
Water is a clear, odorless, tasteless liquid that is essential for most animal and plant life and is an excellent solvent for many substances. Water in many places is contaminated and unfit to drink but people have no choice but make do people trek long distances just to get a pot of water even in places with rivers flowing through, due to peoples negligence and callousness, they are contaminated and unfit to use.
A primary function of water is to serve as a lubricant for example, it is found in saliva and is a substantial component in the fluid surrounding joints water is also in and surrounding body structures such as the brain, spinal cord and eyes. Water balance is maintained between cells and fluid, and the output depends on kidney functions and body insensible perspiration (expired air from the lung is saturated with water vapor, and evaporation from the skin. Water has special properties because of the way these atoms bond together to form a water molecule, and the way the molecules interact with each other when the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like mickey mouse ears. Water has many unique properties that are important to life on earth in this lesson we will explore the thermal properties of water to gain a better understanding of how they support life.
