Synopsis

Compressibility isotherms of argon at temperatures from --25°C down to --155°C and for densities up to 640 amagat were measured. The results, corrected for gravitational effects, are presented. The position of the coexistence boundary line and of the criticalpoint is derived. The experimental second virial coefficients are compared with the theoretical values of the Lennard Jones 6-12 potential. *) For the analysis the authors are indebted to Professor Kis temaker, Director of the Laboratorium voor Massaspectrografie in Amsterdam.
