Recently, Drebushchak (J Therm Anal Calorim 103:753–759, ) has stated that, “Various ways of thermodynamic evaluations can yield different results, contradicting to one another,” and that, “Thermodynamics is not a rigorous mathematical science.” These are radical claims. If they were true, thermodynamics as it is now understood would have to be abandoned. In this paper, I will defend thermodynamics by demonstrating that these statements are incorrect. Thermodynamics remains a valid, self-consistent scientific theory, and we are justified in continuing to rely on its predictions.
