2. In lesson 2, you added ionic compounds to water and observed a temperature change that occurred. The first investigation asked you to use 3 grams of an ionic compound in 20 mLs of water. You repeated this process for five different ionic compounds and recorded the temperature changes that occurred for each ionic compound. Possible variables in this experiment include: I. The ionic compound II. Amount of the ionic compound in grams Amount of water used in mLs IV. Temperature change of the water III. Which of these are controlled variables in the described experiment? O All of the above O I, II, and I O I only O Il and III
