What is it about?
This research paper presents an analytical formula for compressibility based on the Ornstein-Zernike equation for Lennard-Jones potential. The formula is used to determine the bulk modulus and compressibility of various gases, including air and hydrocarbons, as well as the speed of sound at different temperatures. The formula is found to be reliable and consistent with previous studies.
