A 65.0  g piece of gold at 650  K is dropped into 162  g of  H2O(l)  at 298  K  in an insulated container at 1  bar  pressure.  CP,m  for  Au  and  H2O at 298  K  are 25.4 and 75.3  J⋅K−1⋅mol−1, respectively. Calculate the temperature of the system once equilibrium has been reached. Assume that CP,m for Au and H2O are constant at their values for 298 K throughout the temperature range of interest.
