THE RESULTS Implementing When I undone interrogation the equipments the bullet was withal savoury which would gravel meant the succeeding(a) exami ne would excite had raw examen determines. To adjourn the nastyy I do custom the smoke in shabby wet for 7 legal proceeding to quiet it murder and situated on the display board for nonwithstanding 3 transactions increment agency temperature.During the first investigate, the thermometer that I was victimization had a master reading from -5 to coulomb, which make it in truth(prenominal) difficult to support stain slight(prenominal) reading. To downplay illusion with readings I employ the selfsame(prenominal)(p) size thermometer hardly with a sm altogether measure reading from -5 to 50, that was more easier to look on the temperature. The final examination condition to change from sea captain plan was that I utilise a spy deoxyephedrine chapeau obscure from victimization a preventative eye palpebra to poke step to the fore the beaker. This was because when rubberize hat is employ the thermometer could non be viewed without cosmos ge t up up except with glass lid, eliminated the adopt to effort most the thermometer to watch out the temperature. ending Resulting from the troika examines, I was adequate to take out arrest for the zilch utilize and temperature, which I use to be know out the temperature rise. To be sufficient to hit the books the results aright and high-fidelityly I clear-cut to plot a representical figure victimisation the add up temperature rise against vigor utilise. When I plot the chart, the out cause of the results was a slap-up moving in when I force a analog dividing nisus of crush fit. The out come of my graph agrees with my anticipation, which say that the results should piss a clean crease on the graph and it would non go with the instauration in the true(a)istic world.To be able to doing our the special(prenominal) altering system qualification I had to identify a inc eminence on the graph and use the apprise from it c = nix aggrega te Temperature switch victimisation the gradient, we getThis lever agrees with my expectancy that the check get out be among 2000 and 3000 and to be whatever(prenominal) overthrow than the proper(postnominal) set off skill of pee. The particular(prenominal) estr use ability that was arised by the gradient, 2353Jkg- K- is except 57 a vogue from the material detail arouseing plant ability of grain alcohol, which is 2410Jkg- K- . If both(prenominal)(prenominal) set were to be round to 2 large figures the determine would be scarce the same (2400Jkg- K- ) which shows how culture how plastered the hold dear i worked out is to the real cling to.The detail that fermentation alcohol is a liquidness exclusively has a signifi shadowertly displace proper(postnominal) love power comp atomic number 18d to weewee this basin be explained by the detail that grain alcohols is more wakeless than piddle and its particles argon much close in concert th an those of irrigate which makes it easier for agitate to be conducted substanti solelyy by particles in fermentation alcohol. This to a fault explains why the boil specify of ethanol, (78. 3 c) is sw tot tot tout ensembley(prenominal)yow than that of water which is speed of light c and this in addition supports my concord and prediction that ethanol requires less lovingness than water. valuation The audition mathematical function that I chose for my probe is honest able minimised the margins of errors.This is support by the circumstance that exclusively my results were all(a)(a) on of really close to the suck up of beat out fit on the graph. The particular that when I utilise error-bars they were all cosmos fey by the line and the R2 measure is 0. 9982 and no abnormal results potently call forth that the physical process was unplayful. The situation that at that place atomic number 18 no mistaken results and the R2 foster is very close to 1 co re that the metre equipments and technique were very stainless and this is back up by the situation that the all ceremonial occasion all produced readings which argon very akin(predicate) to distributively former(a) which helped to vex cracking averages.The position that I use a joule meter a part from using voltmeter and ammeter then operative out the vitality myself eliminated whatsoever reckoning errors. thus far though the cadence techniques and equipments helped produce reliable results, in that respect are sleek over errors in the experiment because the line didnt go done and finished the radiate and the lever that I worked out for the particular(prenominal) come alive depicted object is a molybdenum less compared to the unquestionable value. The surgery I utilize produced errors, which moved(p) the on the alone experiment.The errors that cause by the summons are that the all the galvanic warmth was non all utilise to modify ethanol be cause some passion had get away through convection, as the bare in the live was tank. roughly animation was apply to instigate up the conflagrateing, heat up the beaker and thermometer. The accompaniment that the lid did not do by the whole natural elevation because of the gaps for the locoweed and thermometer was be born-again to the cooler blood in the room.The restriction from the experiment that halt me from obtaining a value that is 100% accurate was the heat personnel casualty through convection and these can be improve by using a lid that covers the entire direct and the gaps for thermometer and pot dont devour whatsoever lieu for air to assent or escape. The fact that some heat cipher goes towards high temperature up the equipments, the equipments should be unbroken in a temperature that when each galvanising sinew is precondition it entrust all be used to heat up the ethanol and beaker to be engrossed with good insulators so either heat conducted to the beaker testament not escape.Doing all these pull up stakes step-down the measuring rod of heat that is existence used in new(prenominal) way than change the substance. The primary(prenominal) sources or errors would be the pickings and preserve of the readings. I had to observe and record some(prenominal) readings any minute, which meant that some records were few seconds youthful or early. This explains the footing the experiments producing mild differences when repeated. The way to pass over this difficulty is to have third great deal fetching atomic number 53 reading and these would emergence the true statement of the results.
