WebbYou should observe the rubbing alcohol evaporated the most and the orange juice the least. Each liquid evaporated a different amount because each has a different molecular structure and density. WebbCompared to water, alcohol has a lower heat of evaporation. That means that for the same amount of liquid, more heat transfer occurs during the evaporation of water compared to the alcohol. However, this does not fit your observation that alcohol has a greater …

WebbEvaporation provides the energetic fuel that drives drinking bird. The hypothesis of this experiment is that ethanol, having a quicker rate of evaporation than water, will cause the drinking bird to drink faster. Thus it is expected that the more alcohol, the better, as far as drinking bird is concerned. Webb8 feb. 2024 · If bottle is open, the vapor escapes without ever getting saturated like wipes in closed box.
