Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer

He first published this short story “Courage” in the year 1996‚ two years after the new political party was put in place and democracy evolved (Vladislavic‚ 1996). In this essay I seek to critically examine the characteristics of My Old Becker‚ a man who arrives in a black community and is alienated because of his white skin colour. I argue about how his way of dressing

disturbance in liquid. For example if the ball is dropped into water‚ its energy will affect the water‚ causing some amount to splashed out. When the ball is released from a height‚ its initial potential energy combined with the gravitational energy form a kinetic energy‚ which transmitted to the water. So I will investigate the relationship of drop height of the ball and the amount of water splashed out. Research question: How does the volume of water splashed out depend on drop height of the ball?

A 2007 study finds that discharge of untreated sewage is the single most important cause for pollution of surface and ground water in India. There is a large gap between generation and treatment of domestic waste water in India. The problem is not only that India lacks sufficient treatment capacity but also that the sewage treatment plants that exist do not operate and are not maintained.[1] The majority of the government-owned sewage treatment plants remain closed most of the time due to improper

Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers

called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen and Oxygen. This HHO GAS is then sucked into your engine and mixed along

Topic 6 Water Quality and Water Management What determines water quality? Drinking water should be colorless‚ odorless and flavorless; this means that there are no organisms and sediments in the water‚ but it does not mean that if your drinking water look‚ smells and taste clean‚ that does not mean that there is nothing else it. Water also contains dissolved solids: •Sulfur •Calcium •Magnesium If water contains a lot of dissolved calcium and magnesium it is called hard water
