摘要: Synopsis Compressibility isotherms of argon at temperatures from −25°C down to −155°C and for densities up 640 amagat were measured. The results, corrected gravitational effects, are presented. position the coexistence boundary line critical point is derived. experimental second virial coefficients compared with theoretical values Leonard Jones 6–12 potential.
