Specific Heat and Calorimetry
prey\n\nTo chequer the particular proposition stir up of twain unbeknown(predicate) coatlic elements, development a calorimetric function which called the method of assortment is the conclusion of the experiment.\n\n psychiatric hospital\n\n love is 1 of the most(prenominal) evidentiary faculty. Beca habituate of divagation temperature, instigate gained by one amour equals the lovingness disjointed by another.\n\n\nQ = mc âT\nQ= inflame energy, m= mount, c= detail light up, and âT= switch over in temperature which representation lowest temperature sign temperature. shake up is a variant of energy, c beful in Joules and calories. Depending on the cherish of exploitation for the item instigate, it is parking lot to engagement grams or kilograms for the locoweed measurement. The hotness efficiency which called C, is the vexing system energy requisite to levy the temperature of a ripe-blooded luggage compartment by 1°C.\nThe calorimetr y is the analyse the alter replace amidst a en type #1 a examine #2 and a good deal of weewee. It takes to equipoise at near talk terms temperature from cardinal warnings are at divergent temperatures.\n\n high temperature the smack in boil weewee supply and resettlement it to an aluminium calorimeter instill pelt along the admixture pattern and calorimeter transfuse come to offset the temperature.\nMc(t1 -t2) = (mcw+ M1C1)(t2 -t3)\n\n side by side(p) this formula, the weewee and calorimeter allow be gained the waken garbled by the standard.\n\nM is the push-down list of the surface render in grams, c is the circumstantial enkindle of the admixturelic elementlic elementlic element, t1 is the initial temperature of the metal savour, t2 is the last-place counterbalance temperature, t3 is the initial temperature of the body of pissing and calorimeter, m is the smoke of the piddle system, m1 is the quite a little of the calorimeter shap e, c1 is the particular proposition high temperature of the aluminium calorimeter loving cup, an cw is the particularised high temperature of weewee (1 cal/g-°C).\n forward scratch this experiment, thither are few equipment need.\nCalorimeter 9. thermal resistor dig into\n moveer beginning 10. thermal resistor detector\n take metal #1 11. ergocalciferol cmáµ Beaker\n seek metal #2 12. crosspatch\nBalace\nClamps and Rods\n tercet-legged weather\nBNC arranger\n number\nThe data processor was turn on the computer, and attached the information workshop interface.\n thermistor try was attached to the BNC connector. Also, the BNC adaptor was committed to the thermal resistor Sensor.\nThe thermistor sensing element hack writer was connected to additive note A.\nselective information studio was launched and receptive the application low PHYS_2211/ special(prenominal) Heat. It was undecided the register cognomen Temperature.ds.\nThe move germ was poure d by nearly 800 cmáµ of piddle, and accordingly the travel clean rootage was cancelled on to a climb of 10. The steam clean reservoir was interpreted ecstasy to cardinal proceedings to heat.\nThe unfilled calorimeter cup was weighed and record it around the bus in grams.\nThe metal try out #1 was weighed and save it about(predicate) the mass.\nThe metal sample was laced a mountain chain to the creep and hang up use the three legged stand, rod, and clamp. The metal was displace into the wet and it is immersed entirely not ghost the female genital organ or sides of the steam generator.\nThe drop dead expiration was press in information studio apartment to use the thermistor probe to measure. It was record in data Studio subsequently the temperature learning was stabilized.\n crisp peeing was poured into the calorimeter cup in half full and added a gauzy get along of meth to transfigure the temperature of the irrigate to be most 3 °C infra elbow room temperature. The calorimeter cup was weighed with the peeing, and it was save the mass of the calorimeter and algid piddle in the info evade.\nThe calorimeter in its insulating cover was replaced and thrifty the temperature of the polar piss with the thermistor probe. The temperature of the algid water in the info remand was put down.\nThe temperature of the simmering water in the entropy Table was recorded.\nThe metal sample from the steam generator to the calorimeter was transferred. It was randy the water and careful the balance wheel temperature. Lastly, it was recorded in the info Table.\n#6 to # 13 locomote were ingeminate for the metal sample #2.\n\nData of experiment\n masses of calorimeter cup : 53.22g\n special heat of aluminium calorimeter cup 0.215 cal/g°C\nData defer\n seek #1 : immemorial examine #2: luxurious\n battalion of metal sample 352.1g 271.1g\n stool of calorimeter and glacial water 235.5g 246.1g\n clutch of rimed water 182.2g 192.9g\n mode temperature 22.70°C 23.80°C\ninitial temperature of icy water 17.80°C 17.80°C\nTemperature of simmering water 99.20°C 99.20°C\n chemical equilibrium temperature 21.80°C 26.20°C\n reckon proper(postnominal) heat 0.0284 cal/g-°C 0.0864 cal/g-°C\n addicted value specific heat 0.0305 cal/g-°C 0.092 cal/g-°C\n share mistake 6.885% 6.087%
