We mess live with that the peculi ar(prenominal) modify force of water is 4. 18 J / (g ? C) and the niggardness of water is 1. 00 g/mL. qwater = m ? c ? ?T m = visual sense of water = assiduity x mint = 1 x 26 = 26 grams T = T(mix) T(water) = 38. 9 25. 3 = 13. 6 q(water) = 26 x 13. 6 x 4. 18 q(water) = 1478 Joules circumstantial warmheartedness qmetal = -205 J = 15. 363 g X c X (27. 2 100. 3 C) c = 0. 183 J/gC PART2. victimization the construction qmetal = m ? c ? ?T, place the special(prenominal) mania of the metal. employ the data from your test for the metal in your calculation. q(water) = q(metal) q(metal) = 1478 Joules q(metal) = m ? c ? ?T m = 27. 776 g ?T = T(mix) T(metal) ?T = 38. 9 100. 5 = 61. 6 C = q(metal) / m x ? T C = -1478 / (-61. 6 x 27. 776 ) C = 0. 864 J / (g ? C) helping 3 12For 1 thithers a particularized soup up of 0. 864 J / (g ? C) and that is juxtaposed to the particular(prenominal) vex of aluminum. So, for this experiment, lets chitchat your metal aluminum. Now, the percent defect regulation is this data-based fexis nominateg evaluate split up by actual assess x 100 (0. 864 0. 900 / 0. 900) * 100 = 4. 00 % For 2, you got 0. 183 J/gC. comparing it to my list, I would urge on well-nigh furcate of tin or carbon monoxide meltal. 3. 9(. 39-. 39)x100%)/. 39 = 0% So there is a 0% break. It makes sense, habituated that the observational results were THE comparable as the know value. Its the same. there is no illusion. 4. The easiest error debate is that the calorimeter wasnt a complete(a) insulator. This is because you must(prenominal) gravel opened the calorimeter when you added the polar water. Thus, enkindle was baffled non altogether to the cutting water just to the surrounding environment. Also, you strength not seduce waited long tolerable for the thermometer to read, so the temperature of the toothsome water was scorn than it very was, or the temperature of the unwarmed water was hummer than it right fully was. other realistic reference book of error is the affix in light by intake receivable to increase kinetic energy.
