A hat copper cylinder of mass m = 300 gr is dropped into an aluminum beaker of mass m 150 gr, containing water with mass my=200 gr. The initial temperature of the water and the beaker is 20 C and the initial hot copper temperature is 771 C. Assume that the above system is thermally isolated and water is not vaporized. Calculate the final system temperature. Use the following specific heat values: C=1 cal/gr.K, G=0.215 cal/gr.K, =0.0923 cal/gr.K
