Does water mixed with salt evaporate faster than water mixed with sugar?

Question

ScanSolve AI Tutor · Accepted Answer

Herman's experiment involved comparing the evaporation time of water mixed with salt to water mixed with sugar, while keeping other factors like the amount of water, the amount of dissolved substance, and the heat source (small flame) constant. He prepared three bowls with salt water and three bowls with sugar water. He measured how long it took for the water to evaporate from each type of mixture. This setup allows him to investigate the effect of the dissolved substance (salt vs. sugar) on the evaporation rate. The question that Herman's experiment can best answer is: Does water mixed with salt evaporate faster than water mixed with sugar? The other option, "Does the size of a flame used to heat water affect the time it takes to evaporate?", cannot be answered by this experiment because Herman used a small flame consistently for all trials, meaning the flame size was a controlled variable, not an independent variable. The correct option is: Does water mixed with salt evaporate faster than water mixed with sugar?
