11. A student wants to test the time it takes a teaspoon of salt to dissolve in 100 mL of
water at three different temperatures. He places 100 mL of water in three different
beakers and heats them to 10°C, 23°C, and 80°C. Next, the student adds the same
amount of salt to each of the three different beakers. He does not stir the samples. He
measures the time it takes for the samples to completely dissolve (which means he sees
no particles of salt floating around).
What is the independent variable in this experiment?
O amount of salt
amount of water
O temperature of the water
time it takes salt to dissolve in water
