- The simplest assumption which suffices to express the small deviations of gases and vapours from the ideal state at moderate pressures is that the coefficient a in the expression for the capillary pressure varies
**inversely**as some power of the absolute temperature. - At barometric pressures such as exist between 18 and 36 kilometres above the ground the mobility of the ions varies
**inversely**as the pressure, whilst the coefficient of recombination a varies approximately as the pressure. - By geometrical consideration it can be shown that the angle subtended by p, as seen from F, must be
**inversely**as the square of its distance r. - He found that the susceptibility for unit of mass,.K, was independent of both pressure and magnetizing force, but varied
**inversely**as the absolute temperature,. - The conductivity, which varies as the product of n into the mobility, will thus vary
**inversely**as the pressure, and so at 36 kilometres will be one hundred times as large as close to the ground.
