0. Consider a 600 g metallic cylinder initially at 90 °C is added to a calorimeter. The mass of the inner aluminum cup is 65 g and the mass of water is 180 g. The initial temperature of the water and cup) is 20 °C. After the hot cylinder is added to the calorimeter, the equilibrium temperature is 48 °C. Calculate the specific heat of the cylinder and identify the metal.
