An aluminum calorimeter with a mass of 100 g contains 250
Chapter , Problem 19(choose chapter or problem)
An aluminum calorimeter with a mass of 100 g contains 250 g of water. The calorimeter and water are in thermal equilibrium at 10.0C. Two metallic blocks are placed into the water. One is a 50.0-g piece of copper at 80.0C. The other has a mass of 70.0 g and is originally at a temperature of 100C. The entire system stabilizes at a final temperature of 20.0C. (a) Determine the specific heat of the unknown sample. (b) Using the data in Table 11.1, can you make a positive identification of the unknown material? Can you identify a possible material? (c) Explain your answers for part (b).
