August 27, 2014 Cody wanted to know how much heat was released from a reaction of steel wool and vinegar. He placed a thermometer inside a cup that held the steel wool and vinegar. The cup was covered to prevent any loss of heat. Which control should be used as a comparison for Cody’s experiment? A. An empty cup with a cover and a thermometer B. a covered cup containing steel wool, water, and a thermometer. C. an open, empty cup containing only a thermometer D. an open cup containing similar amounts of steel wool and vinegar.
