A combination of 0.250 kg of water at 20.0 degrees C, 0.400kg of aluminum at 26.0 degrees C, and 0.100 kg of copper at 100 degrees C is mixed in an insulated container and allowed to come to thermal equilibrium. Neglect any energy transfer to or from the container and determine the final temperature of the mixture.
