Question

the passage below describes an experiment. read the passage and then follow the instructions below. eduardo filled six bowls with one cup of water each. he dissolved 20 grams of salt in each of three bowls and 20 grams of sugar in each of the other three bowls. he put one bowl on a stand over a bunsen burner, which he set to produce a small flame. the heat from the flame helped to evaporate the water. eduardo measured the amount of time from when the water started to boil to when the water had completely evaporated. he repeated this test with the other five bowls. identify the question that eduardos experiment can best answer. does water mixed with salt evaporate faster than water mixed with sugar? does the size of a flame used to heat water affect the time it takes the water to evaporate? does water mixed with salt or water mixed with sugar boil at a higher temperature?

Explanation:

Eduardo has two sets of bowls - one with salt - water mixture and another with sugar - water mixture. He heats them with the same small - sized flame and measures evaporation time. So, he is comparing the evaporation rates of salt - water and sugar - water mixtures.

Answer:

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