A very hot piece of iron with mass 1.5kg and initial temperature 755 degrees celcius is placed into a tank of water with total water mass 3.0kg and initial temperature 20.0 degrees celcius. Assume the system is thermally isolated and neglects the heat transfer to th tank. If the irons specific heat is one tenth of the specific heat of water, what is the final equilibrium temperature for the iron and water?
