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

Task 3 P3 - The potential effects of discrimination There are lots of potential effects related to discrimination. It includes things like disempowerment‚ low self-esteem and self-identity and also marginalisation. I am now going to explain these effects and connect them with a case study. Disempowerment is when a person or group of people may be made to feel less powerful or confident. Some people may try to fight against the discrimination causing an argument but many people do not and they lose

on the desalination of water. The desalination of water is very important to human and animal life. For centuries humans have used the process of desalination to obtain water safe for consumption.Various methods of desalination have been produced however only some of those methods are widely used today. Although there are numerous methods of desalination all of them involve three liquid streams: the saline feedwater (seawater or brackish water)‚ low-salinity product water‚ and very saline concentrate

Resting membrane potentials Definition: Large nerve fibers when not transmitting nerve signals is about 90 millivolt. That is‚ the potential inside the fiber is 90 millivolts more negative than the potential in the extracellular fluid on the outside of the fiber. The Na+-k+ pump also causes large concentration gradients for sodium and potassium across the resting nerve membrane. These gradients are the following: Sodium ( outside): 142 mEq/L Sodium ( inside): 14 mEq/L Potassium ( outside):

Egg Osmosis Lab The purpose of this lab was to demonstrate an example of a spontaneous reaction and its connection to metabolism; in this case it was osmosis. The procedures that we used to complete the experiment were taking five eggs that had been soaked in a sucrose solution and then placing each one in containers of sucrose that each had different levels of concentration. The mass of each egg was measured before being placed into the solutions and then every 10 minutes after until they had soaked

Part A: Title: Diffusion Diffusion is the spontaneous movement of particles from where they are more concentrated to where they are less concentrated. For this experiment‚ a 14 cm glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to measure the time it took for the food coloring to get to the bottom of the cup. The average diffusion rate was .78 cm a second. If a different color was used‚ I do not think it would have made a difference
