Abstract :The paper presents a remarkable application of the advanced thermodynamics education platform to the molar Gibbs energy G for basic particles in neat fluids. From the G, named also as the chemical potential, and the monomer fraction density Dm functions the Monomer Quantum Volume Vq (T) may be computed. The Vq (T) variable reflects the quantum uncertainty of basic particles positions in atomic and molecular fluids. It has proven to be universal for all fluid’s densities at a fixed temperature T. An extraordinary precision of modern thermophysical databases, such as the NIST Webbook, permits an estimation of the Monomer Quantum Volume values millions times lower than the atom’s volume! By studying the Vq (T) function the students can estimate the quantum uncertainty effects in pure fluids for a total range of their existence up to thousands of Kelvin! The enthalpy data normalization has proven to be very efficient. The advanced platform is highly useful and informative for thermodynamics education. For students it is very educative to study and utilize the author’s computer aided big thermophysical data analysis method to form their vision of the atomic and molecular quantum states distribution in pure fluids.
