What is water? If you ask anybody they would say that it’s something that we just drink, but they’re wrong. There is so much more to water than many knows. Webster defines water as a major constituent of all living matter. What that means is water is that keeps us alive. According to pubchem.gov water is a chemical substance that is essential to all life. Pubchem.gov also states that water is made up of two oxygen atoms and one hydrogen atom. The atom water is Polar. What that means is that the oxygen atom hogs up all the valence electrons. Depending on where the atom is on the Periodic Table says how many valence electrons they have. Every atom wants eight valence electrons so sometimes they share, but oxygen doesn’t share well.Physical Properties of water. Most people cannot list every single physical property. As said in www.physicalgeography.net some physicals properties of water are a boiling point of 100°C, a freezing point of 0°C, a high surface tension, a low viscosity, and water is strongly cohesive. Most people know what a boiling point and freezing point are but some don’t know what viscosity, surface tension, and cohesive mean. Viscosity is the measure of the resistance of a fluid to deformation under shear stress. Water does not have much resistance so that means it has a low viscosity. Something with a high viscosity would be like honey. Next is surface tension. According to https://www.thoughtco.com surface tension is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid. The last thing that many would not know is the term cohesive. A molecule being cohesive means that it sticks to other molecules really well. Some example of high cohesive elements is _. These are the main physical properties of water. Where do you find water? Most people know that water is everywhere. Water is even inside humans. A human body is composed of about 60% water and the 40% is multiple things. According to https://www.everydayhealth.com/, the human body uses the water for all the cells, organs, and tissues. They use water to regulate temperature and other bodily functions. Your body loses water through breathing, sweating, and digestion so it is very important that you keep replenishing your body with water. Another use of water in your body is to protect joints, tissue, and your spinal cord. The water acts as a cushion for your joints and spinal cord. The last thing that water does for your body that is very important breaks in food and aid in digestion. As some may know, digestion starts with saliva, the basis of which is water. Another way that the water helps with digestion is it cleans out the kidneys and flushes out the waste. As you can see water is very important for your body and should always keep your body replenished with water.What state of matter is water found in? Water is the only element that is found in all states of matter in nature. Water is solid when it is frozen and turns into ice and is a gas when it is boiled and turns into water vapor. The last form that water is usually it is a liquid. One would think of water as the liquid that they drink but there is so much more. Water is found in a gas, liquid, and solid in nature all the time. It is nice in the winter, rain in the spring and water vapor on hot days in the summer. Almost every element goes through all three states of matter. They all can be a solid, liquid, and gas, except helium. As said in http://scienceline.ucsb.edu helium is the only element that cannot be in all states of matter. Helium is only found in the solid and gas state and not the liquid state. As you just read you can tell that the states of matter are solid, liquid, and a gas.What else can water be used for? Water is used in many solutions. A solution is a mixture containing a solvent and at least one solute. Some other mixtures are colloids and suspensions. A colloid is a mixture containing small, undissolved particles that do not settle out, and a suspension is a mixture in which the particles can be easily separated by filtration or settling. In many solutions, water is the solvent. Water can dissolve so many substances and that is why it is sometimes called a “universal solvent.” Pearson Interactive Science states that life depends on water solutions. Nutrients used by plants are dissolved in water in the soil. Water is also the solvent in blood, saliva, sweat, urine, and tears. Solutions don’t have to always have water in it. Solutions can have any element. A solution could be basically anything. Another use of water in cleaning. Humans have always used water to clean themselves. The last very important use of water is for washing clothes. Humans now put clothes in a washing machine instead of hand washing, but water is still the most important thing for washing clothes. When did humans start using ice? It was about two centuries ago in about the 1800s when two wealthy brothers had the idea to help cool their beverages. Then 30 years later they were shipping 12,000 tons of ice half-way around the globe. Almost everyone thought that this was a joke. Ships in Boston wouldn’t even agree to transport the ice because they thought that was being such an awful idea. Back then to get ice people would have to take a ship to arctic and cut out blocks of ice with huge saws. They then would put the ice blocks on a ship and transported them wherever they needed to go. The blocks of ice are so huge and cold that they could just sit on the boat and would not melt. So in conclusion ice has been around for over 200 years and was founded by two wealthy brothers.How long have humans preserved things? According to a recent study by Michigan State, food preservation might just be as old as mankind. Once all food is harvested it will always automatically begin to spoil. To survive, people had to find a way to keep food from going bad. Some of the most popular ancient ways of preserving food were drying the food or freezing it. The ancient Romans in 12,000 B.C. came up with the solution of drying by leaving fruits and others food outside and letting the sun and wind naturally dry it. Before refrigerators and freezers were invented it was much harder to freeze things. People used cellars, caves, and cool streams to help freeze some food. Humans still use some of these techniques today but have used modern technology to increase the efficiency. Today many people have dehydrating machines and freezers in their house to help preserve food. Other ways that humans preserve things in a rather new technique. It is canning. Canning was pioneered in 1790 by Frenchman Nicholas Appert. According to Webster Dictionary, a pioneer means a person or group that originates or helps open up a new line of thought or activity or a new method or. Canning is a process by which foods are placed in cans and heated to a temperature that destroys microorganisms and inactivated enzymes. The heating and then cooling forms a vacuum seal. The vacuum seal can prevent other microorganisms from contaminating the food. In conclusion, humans have always preserved food to keep food from spoiling from freezing to drying.The last way to preserve food is salt. People used salt to help preserve food. According to https://www.thoughtco.com salt works because it dries out food. Salt can absorb the water from foods making the environment to dry for harmful mold and bacteria. How does it work? Well, this works by osmosis. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. Table salt or sodium chlorine is a very common preservative because they are not toxic and very cheap. Salt has so many great uses for preserving food and it is a good thing that humans have found out and used it.So as you can tell the water is very important to humans. Water is very important because it cleans out our kidneys, helps with digestion, acts as a cushion for our joints, and so much more. Water is also the only element that can be found in all states of matter in nature. Water is commonly used in every state of matter in our daily life. We use ice to help relax muscles and water vapor to help open up our sinuses. Water also has many important physical properties. The main physical properties of water include high viscosity, high surface tension, and is very cohesive. Other main physical properties of water include a boiling point of 100°C and a freezing point of 0°C. The last very important trait about water is that it is polar. Polar once again means that it doesn’t want to share valence electrons. Besides water humans have been freezing things for as long as mankind. The most common ways of preserving food are using salt, freezing, drying, and canning. In conclusion, humans have always preserved food and used water ever since the beginning and I encourage you to research more about water and food preservation because it might fascinate you just like it amazed me.
