Water

growth of a plant and if a plant grown from carbonated water could grow more grass than flavored water and tap water. We hypothesised that if we put carbonated water against tap and flavored water than tap water would grow the most because it is just pure water and nothing will harm the plants or interfere with the growing process. The materials that we used to conduct this experiment include three plastic cups, grass seed, tap water, carbonated water and cool blue Gatorade, as well a ruler and…

Our guiding question was: How does the concentration of salt in water affect the rate of osmosis? Osmosis is the spontaneous net movement of solvent molecules through a semipermeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. Osmosis also refers specifically to the diffusion of water molecules. Diffusion is the movement of chemical particles for an area of high concentration to an area of low…

Water is the most common substance in nature. It is everywhere. From space, our Earth appears blue because water takes up to two-thirds of the planet’s surface. It is one of the most important and irreplaceable resources of the world. Sometimes humans do not even realize the importance of water in their lives. Each one of us consumes daily an average of about 300 liters of water. And what we do with it? How much water can we drink per day? How much we use for cooking and hygiene? These all…

(DISTILLATION) Around half of the world’s desalted water is produced with heat to distill freshwater from seawater. The process of distillation mimics the natural water cycle in that saline water is heated, producing water vapor that condensed to form freshwater. In an industrial plant or laboratory, water is heated to reach the boiling point to produce the maximum water vapor amount. To make it economically in a desalination plant, the applied water pressure being boiled is modified to…

clear thing we call water is essential to almost every organism on planet Earth. Water so much more complicated and interesting than most people think. Water is made out of two hydrogen atom and one oxygen atom. Two major characteristics of water is cohesion and adhesion. Cohesion is the attraction of the water molecules to itself. Adhesion on the other hand is the attraction of water molecules to the substance that also have dipolar characteristics. The cohesion of the water also is important…

of water are vulnerable. Lake Erie was toxic enough to kill the fish that once inhabited the great lake and, the constant outlet into the ocean in return polluting the ocean. “Today hardly a creek or a river in the world reaches the ocean without carrying a constant flow of non degradable chemicals from industrial, urban, or agricultural areas” (page 342). Realistically if there is no ocean there are no people. As a civilization people rely on the ocean for more than we realize. When water is…

The percent error of the calculated percent water and accepted value is 3.36%. The mean of the class data for percent water was 50.8% and the standard deviation was 0.0300. Compared to the class results, my percent water was lower, but very close to the mean. The standard deviation has a low number; hence the data are not as spread out from the mean. One source of error that contributed to this percent error was that the hydrate, MgSO_4, may have been heated too long. This is a random error…

Planetary scientist just reported that some water carved rocks high in the mountains probably were once covered in water for the planet of Mars. It is thought that billions of years ago a a giant lake could have been on Mars. On Mars there is a NASA Curiositym Rover . The rover is exploring Mars. It has found streams and ponds on the planet already. The reason there is so much interest in discovering if water ever existed on Mars is because the scientist will know if plant and life form ever…

Symbolic Interpretations of Water Water is the most important nutrient for all life on earth and arguably the most significant factor in economic development. Within Sri Lanka, the entire island’s biome and economy are dependent on two yearly monsoons to supply water to the land. This intense period of rainfall is an extraordinary phenomenon from which culture and tradition is built around. In the novel Anil’s Ghost by Michael Ondaatje, Anil revisits her childhood home in Sri Lanka as a…

ourselves, but to the marine life as well. When we throw our medicine down the drain, in the trash or the toilet, we are polluting the water and environment around us with chemicals that are harmful to the aquatic life. People assume that throwing their drugs in the trash is a good solution to this problem because they aren 't disposing of them in a direct water stream. This thought process is extremely flawed because it will eventually just get absorbed into the ecosystem. A recent study has…
