Answer:• Apply a strip of masking tape, about 3 inches long, to the outside of each jar. Label each vial in writing on the masking tape with the marker. Write the following labels: hot water, cold water, RT water, vinegar, alcohol.
• Add 1 cup of the appropriate liquid to each of the labeled jars. Wear eye protection when working with vinegar or alcohol.
• Add 2 tablespoons of sugar to the pitcher of cold water. Immediately start the stopwatch and begin to stir slowly until all the brown sugar is dissolved. Record how long the process took.
• Add 2 tablespoons of sugar to the jug of hot water, start the timer and stir the liquid at the same rate as in step 1 until all the brown sugar is dissolved. Write down how long it takes.
• Repeat the process of adding the sugar, stirring, and the time it takes for all the sugar to dissolve for the jugs of room temperature water, alcohol, and vinegar.
• Compare your results. Does sugar dissolve faster or slower from one solvent to another? Does sugar completely dissolve in each solvent? How did the temperature of the water affect the time it took for the sugar to dissolve?
