Conservation Of Energy Experiment

Title: Thermal Energy Report Name: Bardia Sepehrnia assignment: 05-10-2011 examine Nr. 1 Purpose: check and prove the conservation of cogency law. entropy collection: In this examine, we got 2 specs of pissings with contrasting temperatures. Thermometer is used to round the irrigate temperature. The book of the water supply should as well as be measured apply scale. In order to do that first we measure the push-down storage of the empty chicken feed and hence we measure the bulk of the glass filled with water. By subtracting the big money 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 provide of water together and we measure the habitual temperature using thermometer. subsequently that we put forward find the temperature change (?T) by subtracting the common temperature from the initial temperatur e. (?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 economy E = m.C.?T to measure the amount of talent transferred for two cold and hot water. E: Transferred Energy J m: Mass kg C: Specific genus Oestrus capableness J/g.OC ?T: Temperature Change OC E cold = 0.0877 × 4.2 × 10.3 ? 3.794 kj E flying = 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 sp irit energy can neither be created nor be ! drop down: 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 lineage 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 gigantic time to measure the temperature which will make the water sang-froid down before measuring is completed. These two atomic depend 18 the main reason of the error...If you want to get a entire essay, order it on our website: OrderCustomPaper.com
