Gravitational Compression

A method of measuring density gradients caused by gravitational compression in gases near the critical region is described. Relative light scattering coefficients of ethane in bombs 40 cm. long increase, remain constant, or decrease in the downward direction, depending upon the mean filling density. These observations have been correlated with the variation of scattering coefficient with density, and show that appreciable density gradients exist. These observations are confirmed by parallel studies of condensation, and serve to explain the flat portion of the liquid–vapor coexistence curve found with a carefully purified system.

Variable Function

Turbidity measurements in the region immediately above the critical temperature are used to calculate values of (∂p/∂ν)T These results show that (∂p/∂ν)T is a continuously variable function of the density to within 0.02 °C. above the critical temperature. The experiments indicate that there exists no region above Tc throughout which (∂p/∂ν)T = 0 in ethylene or xenon.
