1. Results Part 1: When samples of austenitic stainless steel are immersed in a sulphuric acid solution and are taken through a current‚ it may be observed that corrosion products are formed around the electrodes‚ to differing degrees. The reason for this is because when a uniform voltage is applied across the series of interconnected electrodes in the acid solution different potentials are obtained at each electrode and hence different electrochemical reactions take place. The products of these

were given to the employees of the older generation. In some ways‚ the writer argues that this change between the generations is positive‚ as they can make for a more dynamic economy. However‚ they are also the cause of the article’s title‚ "The Corrosion of Character". The work ethics of the employees are no longer valued. They are taken as face value‚ and there is no trust and loyalty. These changes are destructive to the worker’s sense of sustained purpose‚ integrity of self and the trust they

a) Conditions under which corrosion is accelerated‚ and b) Methods of preventing corrosion. Two experiments were implemented to answer these questions and hence reach a definate conclusion.First off let’s look at the background of corrosion and the way in which it occurs.The first hypothesis to answer was‚ ’What affect does water temperature have on the rate of corrosion of iron in sea water?’ The assumed answer was that ’ As temperature decreases‚ the rate of corrosion will decrease.’ Secondly‚

Semester One EEI Water Movement In Plants Jason Ho Ms Butz Group Members: Daniel Turner‚ Long Nguyen 13/05/10 Abstract The objective of this investigation was to determine the effect of one specific environmental condition on the rate of transpiration in plants. This particular investigation looked at the number of leaves in a plant and how it would affect the rate of transpiration in plants. The aim of this investigation was to find out if the larger the number of leaves

Extended Experimental Investigation Cold Pack Year 12 Chemistry Abstract: Cold packs are based on the principle of endothermic reactions‚ which means a reaction that absorbs heat from the surrounding resulting in a temperature drop. Due to this temperature drop‚ cold packs have many benefits when it comes to injuries such as sprains and strains. It cools the local tissue and reduces bleeding‚ swelling and pain. It also aids in a speedy recovery. The most commonly used
