Scientists use the second law of thermodynamics (Clapeyron equation) to calculate the heat of vaporization and directly use it as a test value, demonstrating their trust in the second law.
Later, with precise experimental values, scientists found that the experimental values did not match the theoretical values. The second law betrays the trust of scientists.
The theory does not match the experiment, and scientists dare not speak ill of the second law of thermodynamics. They are a bit afraid of the second law.
Einstein: Entropy theory is the first law for the entire natural science. Scientists dare not criticize the second law, even if the theory and experiment do not match.
