One container holds 0.10 kg of water at 75 ∘C and is warmed to 95 ∘C by heating from contact with the other container. The other container, also holding 0.10 kg of water, cools from 25 ∘C to 5.0 ∘C. Specific heat of water is 4180 J/kg⋅∘C. Estimate the total change in entropy of two containers of water using the actual temperatures to determine the heat transferred to each container and the average temperatures to determine the change in entropy....
