(a) A piece of unknown metal weighs 77.1 g. When the metal piece absorbs 0.229 kJ of heat, its temperature increases from 25.6 °C to 38.4 °C. Determine the specific heat of this metal, and predict its identity (see link to table below). (b) If this same piece of metal at 38.4°C is now added to 51.4 mL of water at 22.7°C, what is the final temperature of the water and the metal (in K)? (Note: The density of water is 1.00 g/mL.) Hint: You should convert temperatures to K.
