A student plans to investigate how different factors affect the dissolving rate of a certain mass of potassium chloride (KCl) in water. The student will test a different variable in each investigation: the diameter of the crystals in millimeters (mm); the temperature of the solution in degrees Celsius (oC), and agitation (stirring) of the solution. The given table shows details and predictions for investigation 1. Based on the predicted dissolving times for trials 1, 3, and 4, and your understanding of the solution process, which statement contains the BEST prediction for the dissolving time in trial 2?
