0.10 kg of copper, initially at 95 degrees celcius is dropped into 0.20 kg of water contained in a 0.28 kg aluminion calorimeter. Both the water and the calorimeter are initially at 15 degrees celcius. What is the final temperature of the system?
+33665 You need to use
MCu*cpCu*(TCu - Tf) = MH20*cpH20*(Tf - Ti) + MAl*cpAl*(Tf - Ti)
where M's are masses; cp's are specific heat capacities (which you don't supply), TCu is the initial temperature of the copper, Ti is the initial temperature of the water and aluminium and Tf is the final temperature.
Once you supply the values of the specific heats you can then calculate the final temperature, Tf.
