One gram of a metallic object of constant heat capacity cp=400 j °k-1g-1 is heated to temperature 500°k. this time it is cooled in two stages. first it is thrown into a large vessel containing boiling water. when it has reached equilibrium with the water, it is thrown into the sea as before. calculate the four entropy change occurs in the cooling processes (a) in the object due to the first cooling. ∆s=-117.21 j/k. (b) in the boiling water. ∆s=136.19 j/k. (c) in the object due to the second cooling. ∆s=-100.68 j/k. (d) in the sea. ∆s=114.48 j/k. (e) what is the total entropy change ∆s? explain why ∆s is smaller or larger than that of the previous problem. ∆s=32.78 j/k. (f) how can we make the total entropy change ∆s = 0?
