A:08) A teaching assistant performs an experiment using an aluminum container, with a mass of 0.150 kg, that contains 0.285 kg of water, all initially at 27.0°C. The teaching assistant then adds a sample of an unknown substance to the water. The sample has a mass of 1.2 kgand an initial temperature of 94.0°C. After waiting until the entire system reaches thermal equilibrium, the teaching assistant measures a final temperature of 32.0°C. What is the specific heat (in J/(kg · °C)) of the unknown substance? You may assume the thermalenergy transferred to the environment during the experiment is negligible.number. tiäl temperature of the water and aluminum? Of the unknown substance?
