Before You Begin: You may either copy and paste this document into a word processing program of your choice or print this page.

Instructions: This is a two-part lab. Be sure to follow all steps given in the lab and complete all sections of the lab report before submitting to your instructor.

Procedure:

Part I: Determining the Specific Heat of a Known Metal

1. Place a plastic measuring trough on top of the digital balance, and press the “tare/on” button so that the mass of the trough will be “ignored.” The digital balance should read “0.000 g” after this step.

2. Measure out 25 to 45 grams of one of the four metals on the trough. This may require several “clicks.”

3. Record the mass of the metal in the “notes” section on the right hand side.

4. Select the trough with the metal to add to the test tube.

5. Select the distilled water in the beaker and add 25 mL to the graduated cylinder.

6. Record the volume in the “notes” section on the right hand side.

7. Select the graduated cylinder with the distilled water to add to the calorimeter.

8. Select the thermometer to place into the calorimeter.

9. Roll over the thermometer with your cursor to observe the temperature of the distilled water.

10. Record the temperature of the distilled water in the “notes” section on the right hand side.

11. Select the thermometer to transfer to the beaker that is being heated.

12. Roll over the thermometer to observe the temperature of the metal.

13. Record the temperature in the “notes” section on the right hand side.

14. Select the clamp holding the test tube to transfer the metal to the calorimeter.

15. Select the stirring rod to stir the metal and water.

16. Roll over the thermometer in the calorimeter to observe the temperature.

17. Record the temperature of the water and the metal (mixture) in the “notes” section on the right hand side.

18. Copy and paste the results of your metal into a word processing document for Part II of...
