Ebook: A New Statement of the Second Law of Thermodynamics

Scientific article. — Online publishing, 2008. – 10 p.: ill.A new statement of the second law of thermodynamics is given. The law leads almost effortlessly, for very general closed systems, to a definition of absolute entropy S, a demonstration that ΔS > 0 in adiabatic processes, a definition of temperature, and a demonstration that dS > δQ/T along quasistatic processes. Entropy is given a clear physical meaning.
