Discussion on the Teaching of the Second Law of Thermodynamics from the Perspective of Dissipated Work
The essence of the second law of thermodynamics is that spontaneous processes related to thermal phenomena in nature are irreversible,and irreversible processes are always accompanied by a decrease in energy and quality.The article describes the second law of thermodynamics in general closed systems by introducing dissipated work,which is from the perspective of energy rather than entropy as usual.The author derived the relationship satisfied by the dissipated work,and then used three simple examples to illustrate that the dissipated work is greater than zero for non quasi-static isothermal processes.These conclusions will help students better grasp the sec-ond law of thermodynamics.
