Water Essay

Anything above 162 qt will not fit, but anything less than or equal to 162 qt will fit in the cooler. Kirsten K’s body would have fit in the cooler because it is 62.6 qt. 2. If 1 ml= 1 cm^3 Therefore, (104 cm)(45.7 cm)(1 cm)= 4,752.8 cm^3 of water will be displaced if the cooler sinks one centimeter lower. 3. Density of Clinton Lake: 1.05 g/cm^3 Mass: Density x Volume (1.05 g/cm^3)(4,752.8 cm^3)= 4990.4 g x (1 kg/ 1000 g)= 4.9904 kg 4. (128 lb)/(2.21 lb)= 57.9 kg 57.9 kg (body)

not the water in the U-Creek is polluted using invertebrates as in indicator? Although there are many ways of measuring water quality, invertebrates are good indicators because the number of invertebrates indicates the ability to sustain life. Invertebrates will thrive in better quality water, whereas in poor quality water, invertebrates will not survive as well. Other indicators of water quality such as dissolved oxygen, pH, nitrogen and phosphorus. Dissolved oxygen is oxygen found in water. A high

Abstract No matter how water came to exist on Earth, there is no denying that it has become the basis for life as we know it. From the largest animal, to the smallest microbe, water is essential. Microbes, in particular, have made water their homes and their diversity within these freshwater aquatic habitats was tested in this experiment and the hypothesis put forward was that cleaner water, pond B, contained a higher biodiversity as compared to dirty water. Water from two different freshwater ponds

every organism on this planet is dependent on water, the most crucial substance needed to support life. But, why is this molecule so necessary when it comes to keeping us and other living things alive. It just so happens that water has several physical and chemical properties like no other liquid, making it very special. Three of these properties are water’s dissolving capabilities as a solvent, water’s heat capacity, and ice density. A water molecule consists of two hydrogen atoms and one

this report is based off is, “What is the water quality of the U-High creek, based on the invertebrates found in the water?” Water quality is measured by levels of pH, nitrogen, phosphorus, and dissolved oxygen. Dissolved oxygen is simply oxygen molecules that have mixed in with water molecules (Riverwatch). First, there are measurements for finding the ratio between oxygen and water molecules. The ratio is milligrams per litre. For every litre of water there should be 1-14 milligrams of oxygen

Water is one of the world’s most precious resources, but only 2.5 percent of it is fresh. Even more astonishing only one percent is easily accessible due to the amounts frozen in glaciers (Schnoor). Water sustainability “could be defined as supplying or being supplied with water for life or, perhaps more precisely, as the continual supply of clean water for human uses and for other living things” (Schnoor). In third world countries such as India and China there has always been a struggle for the

Introduction The purpose for the water/food supply is to know how important it is to humans and animals and how we can save our water/food supplies before it is too late. Having an abundant supply of clean water and healthy food are top needs in an emergency. An ordinarily active individual needs to take not less than two quarts which is equivalent to half gallon of water every day. Water consumption on drinking may depend on the environment, level of health and other factors. Similarly, people

depression in the earth’s surface, usually containing water, and a divider that separates different areas. Here in Colorado we have two main watersheds, but we also have several streams considered watersheds. We are in the Cache La Poudre watershed. A watershed is the transport of different water and it is what is used to drain water into other basins, or oceans or any bigger water masses. It has stream valleys that bring water to other bodies of water, in which evaporate and return to the top. This is

Water Essay “Divided into two separate land areas, and bordered by four of the five Great Lakes, Michigan has the longest shoreline in the continental U.S. - nearly 3,300 miles.” [1] Michigan has a little bit of everything; mountains, hills and flatlands, forests, swamps, rivers, and many lakes, which hold 20% of the world’s fresh surface water. Michigan experiences all four seasons, especially winter in the Upper Peninsula. Water has shaped the state over thousands of years, making it what it is

Abstract: In this lab, water was added into a test tube. Then, a pH-indicator called phenolftaleine was added to the water. The solution was mixed. Then, gasoline was added to the mixture. Gasoline is less dense than water, so the gasoline floated on top of the water. In addition, gasoline is a non-polar molecule and water is a polar molecule, which caused them not to mix. A small piece of sodium was dropped into the test tube. As soon as the sodium touched the water, it floated back up to the top
