The “cooling effect of evaporation” is nature’s most important way of cooling our bodies and also the Earth. How cool is that? The purpose of this technology activity is to measure temperature changes versus time when different liquids evaporate. Liquids will be compared pair-wise (e.g., polar versus nonpolar) to analyze the strength of attractive forces.
