7. Watch the temperature of the thermometers closely. Each partner should watch one thermometer. Once the temperature hits a minimum and starts to increase again, make the final temperature measurement. Record it to two decimal places in the Minimum temperature (C) column. For each liquid, subtract the minimum temperature from the maximum temperature to determine AT, the temperature change during evaporation. 8. 9 Roll the rubber band up the thermometer shaft and dispose of the filter paper in the container in the waste fume hood. Wipe off the temperature thermometer with a paper towel. You may reuse the rubber bands in the next parts of the experiment. a. PART 3:n-Pentane ys. 1-butanol butyl alcohol 10. Repeat Steps 7-11 using n-pentane for thermometer #1 and i-butanol for thermometer #2 Be sure to use two new pieces of filter paper. PART 4: n-Hexane vs, methanol (methvl alcohol) Repeat Steps 7-11 using n-hexane for thermometer #1 and methanol for thermometer #2. Be sure to use two new pieces of filter paper. 11. PART 5: Water vs, methanol (methyl alcohol) Repeat Steps 7-11 using DI water (in a beaker) for thermometer #1 and methanol for thermometer #2. 12. Be sure to use two new pieces of filter paper. olecular Forces- Wi9 Last Updated: 1/14/2019 Page 3 of a2
