Unformatted text preview: Hot- and Coldpacks 2/10/08 Results Equations-q dissolution = q calorimeter + q mixture-H solution = C calorimeter * T calorimeter + m mixture * s mixture *T mixture Percent accepted value mean value error = accepted value x 100 The first part of the experiment involved calculating the heat capacity, C, of a simple styrofoam- cup calorimeter. Hot and cold water of determined temperature were used to calculate C based on three trials and the following equation: C CAL T CAL = -q HOT WATER q COLD WATER where the right side of the equation, q for a mixture of the two temperatures of water, can be calculated thusly: q = m mixture * s mixture * T mixture s H2O = 4.184 J/g o C After three trials, the three calculated values for C...
