An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10°C. Two metallic blocks are placed into the water. One is a 48.5-g piece of copper at 80°C. The other has a mass of 142 g and is originally at a temperature of 100°C. The entire system stabilizes at a final temperature of 20°C. (a) Determine the specific heat of the unknown sample. J/kg - °C (b) Using the data in this table, can you make a positive identification of the unknown material? Can you identify a possible material? The unknown material might bi v ---Select--- aluminum beryllium (c) Explain your answers for pa copper iron silver
