Dense gas research involves studying the behavior and properties of gases at high pressures and densities. This field of research is important for understanding a wide range of phenomena, such as the behavior of gases in extreme environments, the properties of gases in industrial processes, and the behavior of gases in astrophysical phenomena. Researchers in this area use a variety of experimental and theoretical techniques to study the thermodynamic, structural, and transport properties of dense gases. The results of this research are used in a variety of applications, including the development of new materials, the design of chemical processes, and the study of planetary atmospheres.
