And Chemical Properties

Owing to its physical and chemical properties being greatly different from those of any of the liquids which have hitherto been used in the Wilson cloud chamber, mercury has been used in the experiments described in this paper and the condensation phenomena of its vapour at different temperatures observed. Before constructing the apparatus it was considered necessary to get from theoretical considerations some idea about the magnitude of the critical supersaturation for mercury vapour in equilibrium with a drop carrying unit charge. Assuming that J. J. Thomson's formula.where s is the supersaturation of mercury vapour in equilibrium with a drop of mercury of radius a, charge e, density σ and surface tension T, the value of which is assumed here to be independent of the radius of the drop, K the specific inductive capacity of the dielectric surrounding the drop, and R the gas constant for one gramme of weight, all at temperature θ, can be applied to the present problem, this critical supersaturation sm is given by the formula

The Relationship

The author measured surface tension coefficient for liquid with a new experimental apparatus, measured magnetic fluid surface tension coefficient at different temperatures and with different volume of surfactant. By the analysis of experimental data, we obtained that magnetic fluid surface tension coefficient decreases with the increasing temperature and increases with the addition of surfactant volume and reaches a certain stability value. We also obtained the expression of magnetic fluid surface tension coefficient and the temperature or surfactant. This paper discussed the relationship between the liquid surface tension coefficient and the temperature and surfactant from the view of thermodynamics.

This investigation involves the effects of non-ionic surfactant materials on the industrial sodium oleate, sodium naphthenate and their mixtures at different temperatures by the surface tension methods. The effects on the critical micelle concentration (CMC) of sodium oleate were assessed by the Toween 80(T-80) presence, polyethylene glycol, polyether and other non-ionic surfactant. T-80 was proved more effective than other non-surfactant in increasing the sodium oleate CMC at same concentration. Using the optimal composition of sodium fatty acid and the surfactant can reduce the temperature of separation hematite from 43°C to 23°C, achieve the purpose of low carbon and energy saving.
