Temperature and pressure dependence of thermoacoustical parameters of liquid argon and xenon

Thermoacoustical parameters of liquid argon and xenon are calculated over a wide range of temperature and pressure on the assumption that the isochoric temperature coefficient of the bulk modulus is an important factor. The Sharma parameter (S-0), which is the characteristic of molten alkali halides and polymers has also been shown to be the characteristic of liquid Ar and Xe at various temperatures and pressures. A relation between isobaric, isothermal and isochoric acoustical parameters have been examined and analyzed for both the liquids.
