A student takes two beakers filled with 50 mL of water. The water in the first beaker is at 27° C, while the water in the second beaker is at 50° C. The student adds 100 grams of sugar to each beaker, and the time taken for the sugar to be dissolved in each is compared. Which of the following is the independent variable in the experiment? - ANSWER The temperature of the water in the two beakers In an experiment, two Petri dishes are prepared using nutrient agar with an equal amount of tap water in each dish.
