A copper sample (ccu = 387 J/kg•K) of mass me = 75 g and temperature Te = 312ºC is dropped into a glass beaker that contains a mass of water mw = 220 g (cw = 4190 J/kg K). The initial temperature of the water and the beaker is Tw,b = 12.0°C. What is the final temperature of the copper, beaker, and water? The heat capacity (the specific heat times the mass) of the beaker is Cb' = 190 J/K.
