16.29. Set Up: for each object. For water, Solve: (a) The heat flow into the ice is The heat flow occurs at so Q is positive and is positive. (b) flows out of the heat source, at Q is negative and is negative. (c) Reflect: For the total isolated system, and the process is irreversible. 16.30. Set Up: For a reversible isothermal process where T is the Kelvin temperature at which the heat flow occurs. The heat flows in this problem are irreversible, but since is path independent the entropy change is the same as for a reversible heat flow. The heat flow when the ice melts is with Heat flows out of the ocean and into the air The heat flow for the ice occurs at The heat flow for the ocean occurs at Solve: For the ice, For the ocean, The net entropy change is The entropy of the world increases. 16.31. Set Up: and For any engine, with and Solve: (a) (b) For the hot reservoir heat flows out of the reservoir at a temperature For the cold reservoir heat flows into the reservoir at a temperature The total entropy change of the factory is

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
