Evaporation of Alcohol and Water
Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.
Curated OER
Evaporation and Condensation
Students explore how temperature effects the processes of evaporation and condensation and how the air may be polluted by the evaporation of certain compounds. In this temperature lesson students complete a lab and a worksheet.
