A 110.0-g sample of a gray-colored, unknown, pure metal was heated to 92.0°C and put into a coffee-cup calorimeter containing 75.0 g of water at 21.0°C. When the heated metal was put into the water, the temperature of the water rose to a final temperature of 24.2°C. The specific heat of water is 4.184 J/g°C. (a) What is the specific heat of the metal. (b) Is it possible that the metal is either iron or lead? Explain.
