Homework Help: physics

Posted by y912f on Wednesday, February 18, 2009 at 10:13am.

A 0.10 kg piece of copper at an initial temperature of 95degC is dropped into 0.20 kg of water contained in a 0.28 kg aluminum calorimeter. The water and calorimeter are initially at 15degC. What is teh final temperature of the system when it reaches equilibrium?
(Cp of Copper=387J/kg * degC; Cpof Aluminum=899J/kg * degC; Cp of Water=4186J/kg * degC)


someone gave me a very long and complicated formula for this. does anyone know a simple way to solve this problem? thanks for any help
