REPORT FORM Heat Capacity of a Metal (All data should be recorded to the proper number of significant figures) Unknown Number 389 Mass of coffee cups (Calorimeter) 4.65g Mass of coffee cups and 100 mL of water 103.30g Mass of water ( me) (Calculated) Temperature of water (ter) 21.9 C Mass of unknown metal ( md) Temperature of metal () (lt is the same as that of the boiling water) 98.7C Maximum temperature reached after adding metal to water (Thu) 24,0 C Change in temperature of the water (AT Water Trux - Twater) Change in temperature of the metal (ATmel = Tru-Thutad) Calculate the specific heat of the unknown and identify it. (Show calculations) Specific heat of metal (C) Identity of unknown metal 77.11g Calculations: Questions: 1. If equal masses of aluminum and copper are heated with same amount of heat, which would reach the higher temperature? Explain your answer. 2. Equal masses of aluminum and copper are heated to 100and placed in water. Which would cause the water to reach the higher temperature? Explain your answer. 3. What mass of water can be heated from 5.0 C to 52C with 130 cal of heat energy? (The specific heat of water is 1.00 calorie/gC)
