To determine the specific heat of an object, a student heats it to 100 ∘C∘C in boiling water. She then places the 55.4 gg object in a 179 gg aluminum calorimeter containing 129 gg of water. The aluminum and water are initially at a temperature of 19.9 ∘C∘C, and are thermally insulated from their surroundings. If the final temperature is 22.3 ∘C∘C, what is the specific heat of the objectand the type of material?
