An unknown substance has a mass of 0.125 kg and an initial temperature of 94.7. The substance is then dropped into a calorimeter made of aluminum containing 0.285 kg of water initially at 26.6 degrees celcius. The mass of the aluminum container is 0.150 kg, and the temperature of the calorimeter increases to a final equilibrium temperature of 32 degrees celcius. Assuming no thermal energy is transferred to the environment, calculate the specific heat of the unknown substance.
