Evaporation and Intermolecular Attractions

Experiment #8 from Investigating Chemistry through Inquiry

In the Preliminary Activity, you will gain experience using a Temperature Probe while you determine the temperature change as ethanol, C₂H₅OH, evaporates.

After completing the Preliminary Activity, you will first use reference sources to find out more about alkanes and alcohols before you choose and investigate a researchable question dealing with temperature changes as alkanes and alcohols evaporate.
