An expeiment was conducted on block of copper material.In this experiment a copper block of 800 grams
of mass with a heat capacity of 0.15 kJ/K at 98 oC is dipped in river at 9 oC.In the second step the same
copper black at 98 oC dropped into the river from a height of 120 m.After the two process both the copper
blocks at 98oC and 0oC both are combined together.Calculate the total entropy change for the each of
the process.
