Experiment 17: Calorimetry General Chemistry I and II Lab Manual Dakota State University page 179 of 232 Data Collection: In the front of the room are several samples of objects in boiling water, including glass and metal. These have a known starting temperature (what is it?). You will be asked to calculate the specific heat of all of them. To do so, you will want to collect data as follows; (1) If you have not already done so, close the calibration window. (2) Click on “sampling options”. Select “slow” and move the slider until “10s” is selected. This will take a data point every 10 seconds once the run is started. (3) Open “table” and “graph” by dragging the appropriate icons over the thermometer icon. (4) Fill the calorimeter with water, then empty the water out. Without drying, measure and record the mass of the calorimeter. Do not forget to “tare” be balance before placing it on the scale. (5) Fill the calorimeter about 2/3 full of water.
