An unknown substance has a mass of 0.125 kg and an initial temperature of 97.5°c. the substance is then dropped into a calorimeter made of aluminum containing 0.285 kg of water initially at 21.5°c. the mass of the aluminum container is 0.150 kg, and the temperature of the calorimeter increases to a final equilibrium temperature of 32.0°c. assuming no thermal energy is transferred to the environment, calculate the specific heat of the unknown substance.
