Chemistry Name Experiment #16 Date: ___Mods:__ Specific Heat Capacity Partner name

Objective To find the specific heat capacity of a piece of metal

Procedure For each of the two metals (1 metal each day): 1. Mass an empty calorimeter 2. Fill with just enough water to cover metal and mass again 3. Record initial temperature of the cup of water to the nearest .5 or .0 degree 4. Record the initial temperature of the metal by measuring temp of the water in the pot 5. Quickly transfer metal that has been in pot for 1 min to cup

Procedure (con) 6. Record the increase of the temperature to the nearest .5 or .0 degree 7. Dry the metal off and mass it 8. Return metal to pot 9. Repeat Steps 1-9 for Trial 2.

Data Al Trial 1 Al Trial 2 Cu Trial 1 Cu Trial 2 Mass empty calorimeter Mass calorimeter and water Temperature of metal initially Temperature of water initially Highest temp of water after adding metal Mass of dry metal

Calculations Calculate the specific heat of aluminum (Al): - m1 ∆T1 c1 = m2 ∆T2 c2 (leave 10 lines) Percent error (Al) Calculate the specific heat of copper (Cu): Percent error (Cu)

Conclusion We found the specific heat capacity of aluminum to be _________. The actual value is ________. The percent error is _________. We found the specific heat capacity of copper to be _________. The actual value is _________. The percent error is _________. (2 more sentences)
