A student obtains the following data in a calorimetry experiment designed to measure the specific heat of aluminum. Initial temperature of water and calorimeter 70.4°C Mass of water 0.403 kg Mass of calorimeter 0.04 kg Specific heat of calorimeter 0.62 kJ/kg·°C Initial temperature of aluminum 26.9°C Mass of aluminum 0.199 kg Final temperature of mixture 66.2°C (a) Use these data to determine the specific heat of aluminum. J/kg · °C (b) Is your result within 15% of 900 J/kg · °C?
Explanation: Using the energy conservation, it means the heat absorbed by the piece of Aluminium from the heat coming from the calorimeter and the hot water
