![]() It has, as we know, as a measure, the product of the weight multiplied by the height to which it is raised. For dQ of irreversible the equation should be changed into the clausius inequality form which is dS> dQ (irreversible)/T. The equation of dSdQ/T is not an accurate equation, the actual equation should be dSdQ (reversible)/T. This effect can always be likened to the elevation of a weight to a certain height. Irreversible free expansion of a gas in adiabatic condition is not isentropic. In the footnotes to his famous On the Motive Power of Fire, he states: “We use here the expression motive power to express the useful effect that a motor is capable of producing. Carnot used the phrase motive power for work. (3.144), the temperature present in this equation is the temperature of the heat source, which is not equal to the temperature of the working body in the event. The entropy change formula for chemical reactions is Sreaction. One of the fundamental thermodynamic equations is the description of thermodynamic work in analogy to mechanical work, or weight lifted through an elevation against gravity, as defined in 1824 by French physicist Sadi Carnot. The change in entropy measures the difference between the entropy of products and reactants.
