SUMMARY
The initial temperature of the heated aluminum bolt can be calculated using the principle of conservation of energy, where the heat lost by the bolt equals the heat gained by the water and the copper calorimeter. The correct formula to use is Tf = (m1C1T1 + m2C2T2) / (m1C1 + m2C2), but it must include all three masses: the aluminum bolt, the water, and the calorimeter. The user initially calculated a temperature of 541.3°C, which is incorrect due to neglecting the mass of the copper cup and the water in the equation. Properly accounting for all components will yield the accurate initial temperature of the bolt.
