DATA SHEET PART A: Determination of the specific heat of metallic copper (pennies)

Trial 1 1. Mass of the pennies. (35-55g) ____________ g

2. Vol. of water in the calorimeter (100mL)____________ mL 3. Mass of water in the calorimeter ____________ g 4. Temperature of pennies (90-100 OC) ____________ oC 5. Initial temp of water in cal. (20-25OC) ____________ oC 6. Final temp of water in cal (TBD) ____________ oC

7. Heat gained by water ___________ J (line 3) (4.18) {(line 6) - (line 5)} This value is positive because heat is gained.

8. Heat lost by the copper** ___________ J (-1) x (line 7)

This value is negative because this is a loss of heat.

11. Specific heat of copper ___________ J/(goC) (line 8) / [(line 1) x {(line 6) - (line 4)}]

12. Average specific heat of copper ** This heat is a loss and must be negative.

Trial 2 _________ g _________ mL _________ g _________ oC _________ oC _________ oC _________ J

_________ J

63

_________ J/(goC) _________ J/(goC)

PART B: Determination of the specific heat of an unknown metal (nuts)

Trial 1 1. Mass of the nuts. (35-55g) ____________ g

2. Vol. of water in the calorimeter (100mL) ___________ mL

Trial 2 _________ g _________ mL _________ g _________ oC _________ oC _________ oC _________ J

_________ J _________ J/(goC)

3. Mass of water in the calorimeter 4. Temperature of nuts (90-100 OC) 5. Init. temp of water in cal. (20-25OC) 6. Fnl temp of water in cal (TBD)

7. Heat gained by water (line 3) (4.18) {(line 6) - (line 5)} This value is positive because heat is gained.

8. Heat lost by the nuts** ___________ J (-1) x (line 7)

This value is negative because heat is lost.

11. Specific heat of nuts ___________ J/(goC) (line 8) / [(line 1) x {(line 6) - (line 4)}]

12. Average specific heat of nuts _________ J/(goC) ** This heat is a loss and must be negative.

____________ g ____________ oC ____________ oC ____________ oC

___________ J

Based upon the Specific Heat what is the composition of the nuts______________
