A copper block of mass 17.5 kg initially at 481 K is immersed in 31.5 kg of water initially at 298 K.

CP,m(H2O,l)=75.3J⋅K−1⋅mol−1

CP,m(Cu,s)=24.4J⋅K−1⋅mol−1

Assume that the heat capacity of Cu remains constant at its 298.15 K value over the temperature interval of interest.

1) Calculate ΔS for the water.

2) Calculate ΔS for the Cu block.
