An object of mass 48.0 g is initially placed in boiling water so that it is at 105° C. Then the object is dropped into a calorimeter, consisting of 106 g of water in an aluminum cup of mass 151 g, thermally insulated from the surroundings. The initial temperature of the calorimeter is 18.0° C and the final temperature is 43.2° C. Find the specific heat of the object.
