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).
a)Tinitial = 28.6°C
b)Tinitial = ?28.6°C
c)Tinitial = 78.6°C
d)Tinitial = 92.6°C
e)Tinitial = 53.6°C
