Vaporization of Liquids

Vaporization of Liquids

In this experiment we tested the temperature of which each liquid vaporized. In my group, we tested Acetone and Ethanol.

Materials Needed:
5cm^2 of Paper Towel
Liquid of Choice - (Ethanol/Acetone)
Non Latex Rubber Bands
Graphing Calculator
Temperature Probe

Procedure:
The first step that you need to do is attach your temperature probe to your graphing calculator. You choose the option for it to record every .5 of a second, and set it to graph for 2 minutes (120 Seconds). You take the end of the temperature probe and put the 5x5cm of paper towel on it. Use the rubber band to secure it to the probe. Once you have your probe all set up, you dip the end into the liquid and hold it in for about 3 seconds. after this, quickly lay it down flat on the table and do not move it. Drafts in the room can affect your data because the wind can cool it down faster. Once you've got this all done hit start on your calculator and then wait till it gets done. Then record your results.
