If the efficiency of heat engine is defined as η = W/W1, and the reversible cycle is considered to be the Stirling cycle, then, given ∮dQ/T = 0, we can prove ∮dW/T = 0 and ∮d/T = 0. If ∮dQ/T = 0, ∮dW/T = 0 and ∮dE/T = 0 are thought to define new system state variables, such definitions would be absurd. The fundamental error of entropy is that in any reversible process, the polytropic process function Q is not a single-valued function of T, in thermodynamics, the P-V diagram should be P-V-T diagram, and the key step of Σ[(ΔQ)/T)] to ∫dQ/T doesn’t hold. Similarly, ∮dQ/T = 0, ∮dW/T = 0 and ∮dE/T = 0 do not hold, either. Since the absolute entropy of Boltzmann is used to explain Clausius entropy and the unit (J/K) of the former is transformed from the latter, the non-existence of Clausius entropy simultaneously denies Boltzmann entropy.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"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
