To determine the specific heat of an object, a student heats it to 100 ∘C in boiling water. She then places the 87.2 g object in a 173 galuminum calorimeter containing 136 g of water. The aluminum and water are initially at a temperature of 19.8 ∘, and are thermally insulated from their surroundings. If the final temperature is 23.4 ∘, what is the specific heat of the object? Referring to the table, identify the material in the object. Substance...
