affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with the acid. This is because the acid only comes in contact with the particles on the surface of the donut. But‚ if you crush

As Hurricane Sandy bears down on the Eastern seaboard — laden with predictions of drenching rains‚ fierce winds‚ snow and extensive damage — some scientists are pointing out ways that climate change might be influencing hurricanes. No single weather event‚ be it drought‚ snowfall or hurricane‚ is caused by climate change‚ climatologists say. Rather‚ climate change amplifies the intensity or duration of extreme weather‚ akin to “putting hurricanes on steroids‚” writes Amanda Staudt‚ a climate scientist

1 Sound in a Night Club 1.1 Overview Noise in the workplace is a very important aspect to evaluate and make provision for. The consequences of working in an unsuitable environment with regards to noise can be severe and includes the possible risk of permanent hearing damage. In an environment such as a night club‚ the continuous exposure to noise due to the loud music can prove to be dangerous. 1.2 Scope The scope of this project includes measuring and analyzing the sound in Catwalk in order

between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size of the surface area to volume ratio of the solid reactant

through growth‚ more chemical activity will have to happen and the rate of metabolism will also increase‚ which means that more substances have to be taken in and to also be removed. This is where the surface area to volume ratio comes into place; the reason why this ratio is so important is because the surface area of a cell essentially affects the rate of the transferring of useful substances (through diffusion and osmosis etc.) in and out of the organism. On the other hand‚ the total volume of the organism

Assignment 1 Part A. Question 1: Going to the following website http://www.austlii.edu.au / and locate the Mildura case: the full citation of the case is: Mildura office equipment & supplies Pty Ltd v Canon Finance Australia Ltd [2006] VSC 42 (16 February 2006) Explain briefly how you found it. There are many way to look for the case .But in my opinion the best way to find it exactly is step 1 firstly Go to the website http://www.austlii.edu.au /.

Background information: 1) What is diffusion? Movement of a particular type of molecule from an area of high concentration to an area of low concentration. 2) How is diffusion used by living cells? Living cells bring in food‚ water and oxygen‚ and excrete wastes through the process of diffusion 3) List two body systems in vertebrates that are dependent on diffusion Digestive system and respirational system 4) What is meant by the term metabolism the chemical processes that occur within a

5. It would be an honor and a privilege to continue my service as a Surface Warfare Officer. I had the pleasure of being assigned to the USS Chung-Hoon during my senior Midshipman cruise. While on the Chung-Hoon‚ I was tasked with assuming the role of conning officer. I was held to the same expectation as my running mate; I was to have in-depth knowledge of the ship’s navigational capabilities‚ report for duty fully prepared to assume responsibilities‚ and‚ at all times‚ be diligent when working
