Question

A 30-kg iron block and a 40-kg copper block, both initially at 808C, are dropped into a large lake at 158C. Thermal equilibrium is established after a while as a result of heat transfer between the blocks and the lake water. Determine the total entropy change for this process.

Explanation:The given data is as follows.     = 30 kg,       = 40 kg     =     = Now, we will calculate the heat energy as follows.                            =                    = 877.5 kJ and,                          =                      = 1003.6 kJ                  =                = 6.531 kJ/K                 =               = -2.747 kJ/K                 =               = -3.142 kJ/KNow, we will calculate the total entropy as follows.                     = 6.531 kJ/K - 2.747 kJ/K - 3.142 kJ/K                 = 0.64 kJ/Kthus, we can conclude that the total entropy change for this process is 0.64 kJ/K.
