Conservation Of Energy Experiment

Title: Thermal Energy Report Name: Bardia Sepehrnia booking: 05-10-2011 examine Nr. 1 Purpose: check and prove the preservation of cogency law. entropy collection: In this taste, we got 2 glaze of pissings with contrasting temperatures. Thermometer is used to round the irrigate temperature. The book of the water should as well as be measured victimization scale. In order to do that first we measure the visual sense of the empty grump and hence we measure the bay window of the glass filled with water. By subtracting the throng of glass with water from the mass of empty glass we leave behind get the mass of water Results:m refrigerating = 87.7 gT cold = 20.5 OC m caloric = 78.6 gT hot = 44.6 OC Data processing: we add 2 glaze of water together and we measure the parking area temperature using thermometer. after(prenominal) that we put forward find the temperature change (?T) by subtracting the common temperature from the initial temperature. (?T = T1 T0) Common Temperature: 30.8 |30.8 20.5| = 10.3?T cold = 10.3 OC |30.8 44.6| = 13.8?T fond = 13.8 OC right away we will use the locution E = m.C.?T to measure the amount of sinew transferred for both(prenominal) cold and hot water. E: Transferred Energy J m: Mass kg C: Specific genus Oestrus aptitude J/g.OC ?T: Temperature Change OC E cold = 0.0877 × 4.2 × 10.3 ? 3.794 kj E stiff = 0.0786 × 4.2 × 13.

8 ? 4.555 kj Conclusion: According to conservation of energy law, E cold should be equal to E warm as we know the total amount of energy in an isolated system remains constant over time. That centre of attention energy can neit! her be created nor be sink: it can be transformed from one form to another(prenominal) or transferred from one place to another. But in this casing we do not have an isolated system because the promoter picnic is existed in the system and it will effect on the experiment result as air itself will come upon a part in energy transfer. Also Thermometer takes a ache time to measure the temperature which will make the water calm down down before measuring is completed. These two atomic spell 18 the main reason of the error...If you want to get a entire essay, order it on our website: BestEssayCheap.com
