During chemistry class your teacher challenged you to dissolve four salts as quickly as possible in a specific volume of water. Each group had to pick a variable to test, a variable that would speed up the dissolving process. Each group had to design an experiment using the steps of the scientific method. The teacher began the experiment with the research question: How can you speed up the dissolution of salt in water. Your group stated: If the water temperature increases, the dissolving time of the four salts will decrease. Your statement can BEST be described as your group's A) hypothesis. B) law. C) theory. D) variable.
