In a calorimetry experiment, it was determined that a 92.0 gram piece of copper metal released 1860 j of heat to the surrounding water in the calorimeter (qcopper = −1860 j). if the final temperature of the copper metal-water mixture was 25.00°c, what was the initial temperature of the copper metal? the specific heat of copper is 0.377 j/(g°c). group of answer choices tinitial = 28.6°c tinitial = −28.6°c tinitial = 78.6°c tinitial = 92.6°c tinitial = 53.6°c
