subject analysis of algorithem Q.5 A block of 200 g of copper is dropped into the container that has 500 g of water. Both are at temperature T= 90 oC. The system is left to cool down slowly. What is the temperature of the system when the heat lost by water and the copper is 2.0 104 J. Neglect any heat gained or lost by the container? Also calculate the total entropy change in the process.
