Temperature dependence of the density of liquid tin

The two-capillary pycnometer method is used to study the temperature dependence of the density of tin in the temperature range from T-melt to 770 K. The measurements are carried out in a superhigh vacuum in higher purity samples. The experimental data are described by an equation of the straight line rho(T) = 7374.7 - 676.5 x 10(-3)T and do not confirm the anomaly (observed previously by some authors) in the form of a minimum on the polytherm of the density of tin in the temperature range from 610 to 700 K.
