Water Is A Chemical Compound Essay

The topic sentence of the article “Small, Yes, but Mighty: The Molecule Called Water” is “Behind water’s peerless punch, and the reason it rather than alcohol or any other lubricant serves as the elixir of life, is the three-headed character whose chemical name we all know: H2O.” This is the topic sentence because it states what the entire article is about, which is water and how unique it is because of it’s molecular structure. I learned several facts about H2O from this article. One thing I learned was that 60 percent of our body weight comes from water. Which proves how important water is for most living things. In addition something else with similar properties would be much bigger and more complex and it would lose the advantages of water.

water covers more than 70 percent of the planet's surface, making our rivers, lakes, oceans,

Water may be a renewable resource, but the world’s supply of drinkable fresh water is being consumed more rapidly than ever before, and most importantly, more rapidly than it can be replenished. Only 2.5% of water on Earth is fresh

fresh water found on planet earth is only a mere one percent (1%) and we have to bear in mind that within that one percent some are found in lakes, rivers, streams and underground aquifers.

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

Attention-getter: Many of us in the United States take for granted that we would always have an infinite supply of fresh water. This is not true; the authors of the Gale Encyclopedia of Science, K. Lee Lerner and Brenda Wilmoth Lerner wrote that, “less than 3% of water on Earth is fresh water” (Lerner and Lerner.)

Water is essential for life as we know it on earth. It is used by plants

The main focus for this lab is to determine why and how water is so essential to life. To begin with, water transports molecules around the body which is in fact very important because afterwards the body gets rid of any waste or toxins in which is unecessary for the body to keep. In addition, water keeps many ogranisms alive and growing, water can range in three different tempetures such as; solid, liquid and gas, in the end all of these occur on the earth. Waters scientific term is H2O which conclude; hydrogen and oxygen atoms, hydrogen is known to be a positive charge and oxygen has a negative charge and together end up having no charge, which makes the molecule polar. The purpose of this study is to dive deep and determine waters importance to life and why it is so essential.

The Importance Of Water To Living Organisms Water is normally the most abundant component of any living organism. As most human cells are approximately 80% water and 60% of the human body is made up of it, it is extremely important in many different ways to both the survival and the well being of living organisms. Evolutionists believe that life probably originated in water and even today thousands of organisms make their home in it. Water also provides the medium in which all biochemical reactions take place. The importance of water to living organisms originates from its many properties including its solvent properties, its high specific heat capacity, its high latent heat of vaporization,

As I sat next to the loud river that was bursting out of the Sylvan Dam, I noticed the water was in an invariable battle with the rocks, crashing and thrashing against each other like medieval warriors scraping for land. I looked around the edges of the river to see the copiousness of colors from the trees contrasting the sinister blue water. The rapids put off a pleasant and dulcet sound that ultimately ended in me having to relieve some building pressure down the trail. After returning to my riverside view, I noticed that farther down the gleaming river, fish were jumping and flipping like delicious pancakes on a griddle. Making the split-second decision to fish, I sprinted to my 1999 black Chevy Silverado, unlatched the tailgate and snatched all of my waterproof fishing gear. Slipping on my Mossberg max 4 Camo Gander Mountain guided series waders is no easy chore. While looking like the most incapable human being ever I finally managed to slip on the foul scum smelling waders that I so dearly should have washed. Feeling like a professional mountain climber, I started scaling the steep inclement of the river bank. Stomping my insulated waders into the frigid dour murky water, I ventured my path out onto a construction of rocks forming a beautiful approach for spotting fish. I released my light green jointed shad Rapala from my St. Croix Legend Elite spinning rod and casted the shad into pooling backwater just off of my rocky approachment. Feeling the vibration of the shad through my rod, smacking against slime covered rocks and ripping through dense weedy areas. I felt aspirant to not get hung up on a rock resulting in a line break, I successfully retrieved my lure. After casting and reeling my line several times and just started zoning out, I was abruptly startled to hear a ruckus coming from the west side embankment. Glancing quickly back to the water to see where my lure was only to hear a loud splash coming from the same place where I first noticed the ruckus. Three deer, with golden brown fur coated enrolled into the water. Realizing that the leaders of the small herd were both doe’s and a younger buck eagerly followed. The buck had a nice six-point rack, with long tines and a wide spread. He kept his

The unique circumstances of planet earth are due to one special ecological feature: liquid H2O. Our planet is far enough away from the sun to keep all of the water on its surface from evaporation yet close enough to prevent it all from freezing. This water is the source and sustaining factor of life as we know it. In fact, the earth is seventy five percent water. Most of that water in contained in earth’s oceans. However, the last few centuries of global industrialization have brought major changes to our shores. Changes that need to be addressed.

Water is a simple molecule created by two hydrogen bonds and one oxygen bond. Water’s formula is H2O because there are two hydrogen bonds and there is one oxygen bond. When these three bonds come together, they become strong and unbreakable. Water is very important. It is important to earth and to your body. Water covers 70% of earth’s surface and your body contains about 60% of water. Water is not just a liquid. Water can also be a solid or gas. Ice is water, but in the form of a solid and a gas is water, but in the form of vapor. Water’s state of matter can change easily due to a temperature increase or decrease. Changing water’s state of matter is a physical change, meaning it can be reversible. So, the objective of this lab is to see how temperature can change water’s state of matter.

In assessing the effect of temperature on the viscosities of water, corn syrup, and acetone, the temperature of the water bath was varied from test to test. At each temperature, with the exception of water at 25.3℃, three trials were run in which the time that it took for the material to travel between the marked lines on the viscometers was recorded. By having multiple data points for each test, a greater level of certainty could be obtained when the time came to analyze the data. For the experimentation of the three liquids, the same set of water baths was used, and the sample materials in the viscometers were not altered or substituted between any of the tests. Additionally, for all of the liquids, the materials were given approximately fifteen minutes after being moved to a new water bath to adjust to the temperature before starting any tests. The information that was recorded for each test included the time that it took for the liquid to travel between the lines on the viscometer, the water bath temperature, and the viscometer constant, k, of the viscometer being used. In addition, in order to convert the experimentally determined kinematic viscosities into dynamic viscosities, data for the mass occupying a pycnometer was gathered for each

Thesis statement: Fresh and clean water is vital to the very existence of the human race.

Water is the lifeblood of every living creature on earth. Approximately 70 percent of the earth's surface is covered with water. Thought the wonders of nature, water can take on many different forms, form the water we drink, to the ice we use to chill a glass of lemonade, to the water vapor used to steam clean equipment equipment. It is easy to understand the significance water plays in our lives, but it may be much more difficult ot understand the water that exists below the earth's surface, called groundwater.
