A glow stick contains a glass vial with chemicals. When the glow stick is bent, the vial breaks and the chemicals react to produce a glow. A science student observes that a glow stick kept in the freezer glows for a longer duration than a glow stick kept at room temperature. What conclusion can be drawn based on the observation? Be sure to note the outcome and test variables in the conclusion
