(b) In an experiment where the specific heat of aluminum is measured using the method of mixtures, a student obtains the following data: Mass of aluminum: m, = 0.2 kg......Initial temperature of aluminum: T, = 27 °C...... Mass of water: m = 0.4 kg.........Specific heat of water: Cw = 4,186 J/kg. 'C.......Mass of calorimeter: m = 0.04 kg...... Initial temperature of water and calorimeter: T₁ = 70°C........ Specific heat of the calorimeter: C₂ = 630 J/kg. C......Final temperature of the mixture: T₁= 66.4°C. Use these data to determine the specific heat of aluminum cx​
