MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An unknown substance has a mass of 0.125 kg and an initial temperature of 90.0C. The substance is then dropped into a calorimeter made of aluminum containing 0.285 kg of water Initially at 24.5C. The mass of the aluminum container is 0.150 kg, and the temperature of the calorimeter increases to a final equilibrium temperature of 32.0C. Assuming no thermal energy is transferred to the environment, calculate the specific heat of the unknown substance. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. J/kg. C Need Help? Read 11
