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°C
Mass of water: 0.400 kg
Mass of calorimeter: 0.040 kg
Specific heat of calorimeter: 0.63 kJ/kg . °C
Initial temperature of aluminum: 27°C
Mass of aluminum: 0.200 kg Final temperature of mixture: 66.3°C
Use these data to determine the specific heat of aluminum.
Your result should be within 15% of the value listed in Table 20.1.
