Identifying Unknown Salts with Calorimetry

Written by Charisa Abstract The purpose of this lab is to identify the unknown salts using the change in temperature to calculate heat realeased. With the given “q” values for all three identiies of the unknowns, one can compare the calculated heat of the reaction to the given value to identify the salt. The unknowns chosen were unknown “C” for trials 1 and 2, and unknwon “A” for trials 3 and 4. The initial temperature was taken before the salt […]

Heat Transfer Lab Experiment

Heat is the transfer of energy between matter due to differences in temperature. In this experiment, heat transfer was studied by calorimetry. The mixing of warm and cool water was observed, as well as the experimental latent heat of fusion. Data: Mixing Warm and Cold Water Table Mass of Empty Graduated Cylinder 86.9 grams Trial 1 Trial 2 Mass of Graduated Cylinder and Cold Water 136.00 g 136.15 g Mass of Cold Water 49.10 g 49.25 Temperature C, Probe 1 […]
