A condensation diagram

Abstract

When a mass of air, saturated with water vapour at room temperature θ1, is expanded adiabatically, the temperature falls to a lower temperature θ2. In general the resulting density of water vapour is greater than the equilibrium value at the temperature θ2and condensation commences. This condensation causes heating of the gas and the temperature rises until finally at some temperature θ3the density of uncondensed vapour is equal to the equilibrium vapour density at θ3. (θ1> θ3> θ2.) Condensation then ceases and the air rises slowly to room temperature by heat conduction through the walls of the apparatus.

New Manifestations of the Strong Nuclear Interactions in Solids

“…This contradicts the history of the development of isotope effect. The first attempt to discover an interaction between neutrons and electrons was made by Dee [11] in the same year, 1932 in which the neutron was discovered by Chadwick [3]. In 1936, Condon [12] pointed out that the existence of a neutron -electron interaction would give rise to an isotope shift in spectral lines of atoms, which was observed for the first time by Aronberg in 1918 [13] in the line spectra of Pb isotopes (see, also [14,15]).…”
