16.32.Set Up:where is the heat flow of 125 J each second. This heat flows into the factory airat a temperature of The heat flows out of the furnace at a temperature ofSolve:The operation of the furnace causes the entropy of the factory toincrease.16.33.Set Up:The reversible process that connects the same initial and final states is an isothermal expansion at from to For an isothermal expansion of an ideal gas and Solve: (a)(b)The isolated system has so the process is irreversible.Reflect:The reverse process, where all the gas in 35.0 L goes through the hole and into the tank doesn’t occur.16.34.Set Up:Heat with comes out of the hot water at and goesinto the cold water at Solve: (a)(b)The isolated system has so the process is irreversible.16.35.Set Up:For each change in temperature the magnitude of the heat flow for each 0.500 kg of water isSince the amounts of water are the same,when one 0.500 kg warmsthe other coolsThe final temperature of the mixture isUsefor each change. Heat flows out of the warmer water and into the cooler water.Solve:and and and The total entropy change is 16.36.Set Up:For an isothermal process of an ideal gas,and For acompression,and Solve:DS521850 J293 K5 26.31 J
