The causes of water pollution Water pollution comes from a myriad of sources‚ both natural and from human activity. The most destructive causes of water pollution are man made‚ however. The largest sources include: The burning of coal in power plants emits ash particulates that contain toxic metals like arsenic and lead. Coal and petroleum also contain sulfur compounds. Combustion generates sulfur dioxide‚ a toxic gas‚ and oxides of nitrogen. When emitted from exhaust stacks‚ these two compounds

the Reactivity of Metals Aim: To prove the arrangements of the metals (Na‚ Ca‚ Mg‚ Al‚ Zn‚ Fe‚ Sn‚ Pb‚ Cu) according to the reactivity series. Background Information: By using various experiment‚ the reactivity of the metals can be deduced by the observation of the reaction. Hypothesis: Metals with low ionisation energy will lose their their electron more easily providing a more vicious and obvious result‚ as compared to the metals with higher ionisation energy‚ as the metals with lower ionisation

Title Impact of water jet Objective The purpose of this experiment is to demonstrate the application of the momentum equation. The force generated by a jet of water deflected by an impact surface is measured and compared to the momentum change of the jet. To relate: • Direct measurement of impact forces • Effect of flow rate and velocity • Effect of various deflection angles Introduction / Theory Newton’s Second law states that The applied forces is equal

Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other purposes‚ including meeting the requirements of medical‚ pharmacological‚ chemical and industrial applications. In general the methods used include physical processes such
