In this lab activity, students use a digital temperature probe to compare the temperature changes when four different alcohols evaporate. The analysis questions provided guide students to connecting the energy changes associated with the change of state with the structure of molecules of substances. Before beginning the lab, students are asked to consider the structural formulas of the alcohols used in the lab: methanol, ethanol, 1-propanol, and 1-butanol. After collecting data for the first three alcohols, students predict the temperature change for 1-butanol and then collect data to test their prediction. The resource linked here is a sample. More complete information, including teacher’s guide and safety information, is available for purchase from Vernier Software and Technology using the link provided on the final page of the sample.
