A 17.7kg piece of zinc at 73 degrees celsius is placed in a container of water. The water has a mass of 23 kg and has a temperature of 13.4 degrees celsius before the zinc is added. what is the final temperature of water?
heat lost by Zn + heat gained by water = 0
[mass Zn x specific heat Zn x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
You have Tfinal as the only unknown. Solve for it.
