Abstract:

A new fundamental equation of state that describes the behavior of the thermodynamic properties of carbon dioxide in the vicinity of the critical point is formulated. In this work, we present an equation of state based on the crossover model that takes into account not only the scaling laws at the critical point but also the classical behavior far away from the critical point. The equation of state is constructed based on the new pressure data measured by Duschek and co-workers. We give the comparison with different set of thermodynamic-property data available, such as the pressure data, the specific heat data.

Keywords:

carbon dioxide, crossover model, equation of state, specific heat, thermodynamic properties.
