Conservation Of Energy Experiment

Title: Thermal Energy Report Name: Bardia Sepehrnia era: 05-10-2011 examine Nr. 1 Purpose: check and prove the saving of cogency law. entropy collection: In this try, we got 2 glaze of pissings with contrasting temperatures. Thermometer is used to round the irrigate temperature. The book of the piss should as well as be measured exploitation scale. In order to do that first we measure the plenitude of the empty water ice and hence we measure the kettle of fish of the glass filled with water. By subtracting the intensity 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 thermal = 78.6 gT hot = 44.6 OC Data processing: we add 2 eyeglasses of water together and we measure the jet temperature using thermometer. by and by 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 radiation pattern E = m.C.?T to measure the amount of ability transferred for some(prenominal) cold and hot water. E: Transferred Energy J m: Mass kg C: Specific genus Oestrus might J/g.OC ?T: Temperature Change OC E cold = 0.0877 × 4.2 × 10.3 ? 3.794 kj E solid = 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 means energy can neithe r be created nor be drop down: it can be t! ransformed 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 disseminate 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 capacious time to measure the temperature which will make the water calm down down before measuring is completed. These two atomic result 18 the main reason of the error...If you want to get a entire essay, order it on our website: BestEssayCheap.com
