The strength of Ammonia Double Essay Example for Free

The strength of Ammonia Double Essay In this investigation I am trying to find out if doubling the strength of ammonia doubles the rate of its diffusion. There are a few factors that may have an effect on the results of this investigation. For example, the size of the test tube, the distances between each piece of litmus paper and the amount of ammonia on the wool. The longer or wider the test tube the more time it will take for the ammonia molecules to diffuse along the tube which would increase the time on the results table. A similar principle would apply to the distance between litmus papers. The ammonia is most likely to reach the litmus paper closest to it first and then to the second as it will take more time for the ammonia molecules to diffuse across the tube. Also each time the ammonia is applied to the wool it must be the same amount for every test carried out, otherwise the test would be unfair. This is because the amount of ammonia affects the speed at which the molecules travel. If too much ammonia is applied then the molecules would move faster along the tube, but if there is less ammonia the molecules would move slowly down the tube. Three additional things that affect the rate of diffusion of the ammonia include molecular size, temperature and the concentration of the ammonia. My investigation is aimed at discovering the effects of doubling the strength (concentration) of ammonia on the rate of diffusion. I think increasing the concentration of ammonia will decrease the amount of time it will take for the litmus paper to turn blue i. e. diffusion will be faster. However, decreasing the concentration of ammonia will increase the amount of time it will take for the litmus paper to turn blue i.e. diffusion will be slower. Doubling the strength of ammonia could have an effect on the rate of diffusion because it doubles the number of molecules, which collide more. Consequently, the particles in a gas will spread out and thus have greater space to move around more quickly and easily. This is how ammonia particles will look in the form of a gas as they collide and spread: To make this investigation a fair test, I am going to space out the litmus papers but not too far apart and evenly spread out each of the seven litmus papers I intend to use. I will also use the same volume of ammonia to make it a fair test each time. The concentration will, however, gradually be doubled. I will start with 0. 5% double it to 1%, 2% and finally 4%. To carry out this experiment using a stopwatch to measure how long it takes for each red litmus paper to turn blue. I will take 1 reading every time a litmus paper changes colour, which will result in 7 readings for every test. Then I will obtain the results taken by two other people in my team and average them out by adding the results up and dividing by 3. This will give me a reliable answer as to how long it took for each of the seven litmus papers to turn from red to blue. So the number of tests to be performed in total is 3 and so by multiplying 3 with 7 will equal 21 results being taken from 21 litmus papers changing colour. These results will be taken in seconds but I shall convert any that are given in minutes by the stopwatch, into seconds. OBTAINING EVIDENCE The table below show my results: The Concentration Of Ammonia Litmus paper no  To perform this experiment safely it was necessary that we wore goggles and used tongs to pick up the cotton wool that had ammonia on it. ANALYSING RESULTS/DRAW CONCLUSION I have drawn a graph on a piece of graph paper to show the pattern in my results. The pattern shows that as you double the concentration of ammonia, the quicker it takes to change colour from red to blue. This is because, as I had predicted, increasing the concentration also increases the number of molecules, which collide more. Consequently, the ammonia molecules spread out to make greater space to move around more quickly and easily. EVALUATING. The experiment appears to have been successful as I acted according to my plans and achieved the results I had expected. My results could be improved by carrying out the tests a few more times, in order to achieve more accurate results. I can conclude from my results that doubling the strength of ammonia doubles the rate of its diffusion. A pattern in my results also showed that a as you double the concentration of ammonia, the average time is twice as less. However, this pattern was not apparent when I increased the concentration of ammonia from 0. 5% to 1%. On that occasion it seems that the time had reduced by more than just a half. The reduction in time was usually approximately by half, but by drawing a line of best fit through my graph, it can be said that doubling the concentration of ammonia does double the rate of diffusion.

Personal Narrative- Varsity Volleyball Essay -- Personal Narrative

Personal Narrative- Varsity Volleyball I first started playing volleyball at a very young age. I was in the seventh grade when my volleyball career started. My sister started playing in the seventh grade and I just wanted to follow her footsteps. My seventh grade year was ok because I had just started out and really didn’t know the game. There was A team and a B team, where A team was better than the B team. I tried my best to be on the A-team, but guess where I ended up, on the B team. No matter what team I was on I never gave up. I was so determined that my eight-grade year was going to be different. Sure enough, I ended up on the A-team in the eight-grade. I thought that was the most wonderful thing in the world; I though all wrong. I did nothing but ride the bench. I hardly e...
