Organic Molecules Organic Matter
633 wordsDissolved oxygen infers to the volume of oxygen that is contained in water. Oxygen enters water through photosynthesis and across the water interface. The amount of oxygen that can be held by the water depends on the water pressure, salinity, and temperature. Gas solubility increases with decreasing temperature; thus colder water holds more oxygen. A reason why freshwater holds more oxygen than does saltwater is because gas solubility increases with decreasing salinity. When there is a change in...

Sulfur Dioxide And Nitrogen Burning Of Fossil Fuels
1,264 wordsWhat is Acid Rain? Acid rain is a form of precipitation that falls to the earth as rain. For rain to be acidic it has a pH level of less than 5. 6. The corrosive nature of acid rain causes widespread damage to the environment. The problem begins with the production of sulfur dioxide and nitrogen oxides from the burning of fossil fuels, such as coal, natural gas, oil and other kinds of manufacturing. When these pollutants are in the air, they react with water and other chemicals, to form sulfuric...

Liquid Water Aquatic Life
655 wordsWhat would the world be like if solid water was denser than liquid water? Density is a property of matter. It is defined as the amount of material that fits in a given space. Denser objects are naturally heavier than objects that are less dense and of the same size. In the same manner that solid objects have density, liquids also have density. In that connection, water is denser than oil. If two objects of different densities come into contact, then the one that is less dense will float on it. T...

Metal Ions Drinking Water
2,316 wordsWater is a tasteless odorless vital element in which 90 percent of all organisms depend on to survive. It is one of the best-known ionizing agents and, is frequently called the universal solvent. Water combines with certain salts to form hydrates. It reacts with metal oxides to form acids and it also acts as a catalyst in many important chemical reactions. Not only is it essential to our health, but it is also crucial in the household and the industrial world. Every day we use water for cooking,...
