5. Once water is vigorously boiling, measure the temperature of the boiling water using a thermometer and record. Be sure to hold the thermometer so that the thermometer bulb is Temperature of immersed in the boiling water but not touching the sides or boiling water (initial bottom of the beaker. The thermometer should be in the boiling temperature of water for 1-2 minutes to allow temperature to reach equilibrium. metal) Remove the thermometer and set it down on the lab bench and let it cool to room temperature 6. After the temperature has been recorded for the boiling water, continue heating the water for another 10 minutes. 7. Obtain two clean and dry Styrofoam cups with a lid. Nestle one Mass of 2 Styrofoam cup inside the other and measure the combined mass of the cups cups + lid and lid. 8. Measure 50 mL of Dl water using a 50-ml graduated cylinder and Mass of 2 Styrofoam pour into the Styrofoam cup. Measure the mass of the water, cups + water + lid cups, and lid. This is your calorimeter. 9. Place the calorimeter inside a 250 ml beaker so that it won't easily tip over. Insert the thermometer (be sure it has cooled to room temperature) through the lid and place the lid on the calorimeter so that the bulb of the thermometer is completely Initial temperature of submerged in the water. Let the thermometer sit in the water water in calorimeter for about 1 minute (to reach thermal equilibrium) and record the initial temperature of the water in the calorimeter.
