A 21.0 gram sample of copper at 96°C was added to 53.0 grams of water at 18°C in a perfectly insulated calorimeter. The final temperature of the copper-water mixture was 20.3°C. Calculate the specific heat of copper using the data.

✔ 最佳答案
Heat change = m c ΔTAssume that there is no heat loss to the surroundings.
Heat lost by the sample of copper = Heat gained by the water
(21.0 g) × c × (96 - 20.3)°C = (53.0 g) × [4.18 J/(g°C)] × (20.3 - 18)
c = 53.0 × 4.18 × (20.3 - 18) / [21.0 × (96 - 20.3)] J/(g°C)
Specific heat of copper, c = 0.321 J/(g°C)
