Specific Heat of a Metal Michael Diaz Ms. Zhort Performed: October 3, 2013 Due: October 24, 2013 Period: 1 Lab Partner: Rocco & Asha Objective: This lab was meant to teach us how to find the specific heat of a metal sample. Materials: * Specific heat set * Balance * Thermometer * Tap Water * Hot plate * Polystyrene cup and a lid * Stirring rod * 250 mL beaker * String (about 15 cm) Procedure: 1. Fill a 250 mL beaker approximately half full of water. Place the beaker of water on a hot plate. Begin heating the water to the boiling point. Turn the hot plate on high. 2. Measure the mass of the metal. Record the mass carefully in Data Table 1 3. Obtain a calorimeter cut. Record the mass carefully in Data Table 1. 4. Fill the calorimeter cup approximately 2/3 with distilled water at room temperature and record the mass in Data Table 1 5. Measure the temperature of the tap water in the calorimeter cup and record in Data Table 2. 6. Carefully transfer the metal to the beaker with boiling water. Boil at least 10 minutes. 7. While the metal is still in the boiling water bath, measure the temperature of the boiling water carefully with a thermometer and record to tenths, one decimal place, in Data Table 2 8. After the metal has been heating 10 minutes, remove the metal from the boiling water bath using the string. Immediately transfer the metal into the calorimeter cup so that the water covers the metal. Cover the calorimeter cup with its lid ASAP. 9. Carefully insert the thermometer through the small hole in the lid. Stir very slowly with a stirring rod and record the highest temperature reached by the water in Data Table 2. 10. Remove the calorimeter lid, retrieve and dry the metal. Return metal to its original place. Pour the water down the sing. Let the calorimeter cup cool
