Measuring Specific Heat for Metals Objectives: 1. Hypothesize about the properties of the metal tested and/or the energy transferred. 2. Calculate the specific heat of the metal using your mass and temperature data. 3. Evaluate the hypothesis and the procedure performed. Hypothesis: If the mass of the metal is greater, then the temperature change of the water will increase. Safety: Glasses must be worn, and loose clothing restrained for the Lab Exercise! Materials: 250mL Beaker Test Tube Calorimeter Burner, Ring Stand, and Wire Gauze Thermometer Balance Procedure: 1. Prepare an appropriate data table. 2. Fill the 250mL beaker about half full. Place it on the stand and begin heating it to the boiling point (100 degrees Celsius). 3. Measure the mass of the zinc to be tested. 4. Place the test tube, with the zinc in it, in the water and continue heating. 5. Fill the Calorimeter with the water to 45mL, measuring the amount of the water in the Calorimeter. 6. Record the temperature of the water in the Calorimeter and the temperature of the boiling water. 7. Quickly pour the metal into the Calorimeter. 8. Stir the Calorimeter slowly with the thermometer. Record the peak temperature reached. 9. Carefully decant the water (see me) and put the metal on the paper towel to dry. 10. Repeat the procedure for a second metal. Analysis: Our data | Trial #1 | Trial | Mass of zinc | 1.99g | 4.01g | Mass of water in Calorimeter | 45g | 45g | Temp. of water in Calorimeter | 20°C | 21°C | Temp. of boiling water | 100°C | 100°C | Peak temp. the water reaches | 22°C | 24°C | How much change in degrees | Δ2°C | Δ3°C | Pat and Jaymie’s Data | Trial #1 | Trial #2 | Mass of zinc | 6.0g | 7.99g | Mass of water in
