Vapor Pressures,rted by the vapor above a pure liquid is dependent upon temperature only and is independent of the fraction of the liquid which has vaporized. If, however, the sample consists of more than one component, the pressure is not independent of the fraction vaporized since the more volatile components eva

Annemarie Perl,Regina Roller-Wirnsberger again, in the foreseeable future, for the determination of atomic weights. Thus, for example, the ratio of the atomic masses .C to .0 has been determined mass spectrometrically to better than one part in 10.. This high precision has shown also that polynuclidic elements (elements with more than one

Temperature Measurement under Pressure,s . evaluation of true pressure and temperature. Up to now, most of the temperature sensors have been developed for use at atmospheric pressure. On the other hand pressure calibration is difficult at temperatures far from room temperature, for instance close to absolute zero. The problem of temperat

Part 1: Mercury Absolute Manometers,a’, is the pascal, which is a newton per square meter. In this chapter, an ‘absolute manometer’ is one which operates as a ‘primary’ instrument; that is, it is constructed to operate so that the pressure can be evaluated directly in the base units of mass, length and time.
