10. Measure the temperature of the ice water using the same thermometer as that used in step 7.
11. Remove the stopper and measure the volume of water drawn into the flask to the nearest 0.1 mL by
pouring the water into a dry 100 mL graduated cylinder.
12. Fill the flask completely with water. Reinsert the stopper to the same depth that was marked in step 3.
13. Measure the volume of water in the flask when it is full to the nearest 0.1 mL using a dry 250 mL
graduated cylinder.
14. Repeat the procedure to obtain data for Trial 2.
