Question 6 • Chemistry
The calorimeter absorbs the 14.0 kJ released by combustion, so use q = 14,000 J. Convert its mass to 1,200 g, then calculate the temperature change: ΔT = q/(mc) = 14,000/(1,200 × 3.55) ≈ 3.29°C. Add this rise to the initial temperature, 22.5°C + 3.29°C ≈ 25.8°C, so the final temperature is 25.8°C.
