cs = (mwcw+mccc) (T3 - T2) ms(T1 ? T3) cs = ((1)(165)+(0.215)(55))(26-21) 195 (84-26) 11310 cs = 825 + 59.125 = 0.072 cal/gCo% ERROR = / Standard ? Experimental/ x 100% Standard = /0.072-0.092/ x 100% 0.092 = 21.7%VII.AnalysisBased on the data above, I can say that the specific heat of material differ depending on the kind of substance. The specific heat for copper for example, after the experiment, became 0.052 cal/gmoC while on the other hand; the lead?s specific heat became 0.072 cal/gmoC. The 2 solids have achieved different results even though the procedure done for both was the same. This is because the different specimens differ in tolerance when heat is concerned. Therefore, the required amount of heat needed to change the temperature of a unit mass of substance by one degree also varies.Although the method mixture is an effective way to measure the specific heat of a given specimen, it is not entirely accurate. The errors in the experiment were primarily due to outside factors such as the wind, weather, etc. Also, the stirrer of the calorimeter added to the mass of the calorimeter which provided inaccuracy in measurement.VIII.ConclusionIn conclusion, I can say that the method of mixtures is a simple but an effective way to compute for the specific heat of specimens. In addition, the experiment helped clarify the concept of specific heat. I have learned that the specific heat is the amount of heat required by an object for it to change its temperature by a certain amount usually by one degree. This was shown when the specimens were transferred from one container to another that differed in temperature. IX.Answer to questions1. The thermometer also gains some of the heat. Neglecting the heat capacity of the thermometer, it causes inaccuracy in the measurement of specific heat. 4. given:Ms = 50 gT1 = 100 CM...
