Using an artificial atmosphere the pressure of water has been determined between 98°.0 and 102°.6 corresponding with pressures of 706 mmHg and 833 mmHg. The vapour pressure can be represented by the quadratic formula: t = 100 + 0.036 973 6 ( p − 760 ) − 0.000 019 590 ( p ...

The vapour pressure of pure benzene at 25^(@)C is 180 mm Hg. The vapour pressure lowering caused by the addition of 2.5 g of a solute ( Molar
Fifty specimens were submerged in the mixture of MMA and MMA–styrene in a container and put inside a vacuum chamber. The samples were impregnated using vacuum and pressure process of 700 mmHg and 34 psi, respectively. The vacuum pressure was maintained for 1 h before the air in the...
Abstract––The vapour liquid equilibrium data at 760 mmHg (at atmospheric ) pressure have been determined experimentally for the binary system, viz, acetone – methanol , at different concentration of calcium bromide .Smith and Bonner type still was used.. The present work involves the measurement...
The variation of specific surface areas with water vapour pressure was found to behave in accordance with the Smith-Topley effect, with a minimum SBET value located at 3.0 mmHg of water vapour. Analysis of the nitrogen adsorption isotherms by the t-method revealed the existence of both micropore...
The ratio nBeO nH 2O at constant temperature was independent of water vapour pressure for pressures between 57 mmHg and 760 mmHg. Weight losses of BeO were a function solely of temperature and water throughput, and can be described uniquely by the equation: log nBeO = 1.62–8.8 × 10 3 T...
