CALORIMETRY (THERMODYNAMICS)
A 0.055-kg mass of lead at an initial temperature of 135 0C, a 0.075-kg mass of brass at an initial temperature of 185 0C, and a 0.0445-kg of ice at an initial temperature of −5.25 0C is placed into a calorimeter containing 0.250 kg of water at an initial temperature of 23.0 0C. The aluminum calorimeter has a mass of 0.085 kg. Find the final temperature of the mixture.
