Thermodynamics of liquids: standard molar entropies and heat capacities of common solvents from 2PT molecular dynamics [PDF]

open access: yes, 2011
We validate here the Two-Phase Thermodynamics (2PT) method for calculating the standard molar entropies and heat capacities of common liquids. In 2PT, the thermodynamics of the system is related to the total density of states (DoS), obtained from the ...
