Calculate entropy change: ΔS = Q/T (isothermal), ΔS = m·c_p·ln(T₂/T₁) (heating), ΔS_mixing, Boltzmann entropy S = k·ln(Ω). Second law: ΔS_universe ≥ 0 for all spontaneous processes.
2D stress state at a point. All stresses in MPa.
Enter the values for the patient or scenario you are assessing. Calculate entropy change: ΔS = Q/T (isothermal), ΔS = m·c_p·ln(T₂/T₁) (heating), ΔS_mixing, Boltzmann entropy S = k·ln(Ω). Second law: ΔS_universe ≥ 0 for all spontaneous processes. Use the entropy change result to inform your clinical assessment.
