Guiding QuestionWhy do liquids evaporate at different rates?
IntroductionHave you ever had a sunburn or high fever? If so, you may have used rubbing alcohol to help cool your skin. The alcohol works because it evaporates quickly and lowers skin temperature. The evaporation of a volatile liquid is an endothermic process that results in a temperature decrease. The magnitude of temperature decrease is related to the strength of intermolecular forces of attraction. Rate of evaporation can be described as the change in temperature divided by the time it takes to reach the lowest temperature
You are watching: Why do different liquids evaporate at different rates
In this experiment, you will investigate factors that determine the strength of intermolecular forces by determining the rate of evaporation for a series of volatile liquids.
GoalsAs you complete this investigation you will:
Use a molecular model kit to build a model to describe the attractive forces between these molecules.
Getting StartedUse the Molecular Model kit to make models of each of the compounds that will be studied in Investigation 1 and consider the following questions as well as those in the PreLab activity.
