How is the interfacial tension of liquid-liquid system measured by pendant drop method?

It is known that the surface/interfacial tension tension can be measured by pendant drop method and the following equation: IFT=deltaro*g*de^2/H. 1/H is function of ds/de (1/H=f(ds/de)). I used...

Why do the strange behaviour exist at the interface of tetrahydrofuran/2-propanol mixture?

I have modeled the surface tension of tetrahydrofuran (THF)/2-propanol mixture at T=288.15 K (xTHF=0.55) by using gradient theory. I take tetrahydrofuran (THF) as a reference fluid. The density...

Does any equation exist for describing the fugacity coefficient of surface phase at high pressures?

I search for equation for describing the fugacity coefficient of surface phase or interface because I believe that different equation is needed for surface phase or interface. I search for the...

Why does the interfacial tension of systems containing water/immiscible liquid (for example water/octane) increase by increasing the pressure?

The interfacial tension usually decreases by increasing pressure, but for water/immiscible liquid interfacial tension increases by increasing pressure.

Does any model exist which can support the viscosity and thermal conductivity of fluids up to very high pressures?

It is known that many viscosity and thermal conductivity models are only applicable for atmospheric and saturation conditions. On the other hand, very high pressures (higher than 500 bar) is a...

Do we have any criteria whose value shows how much a liquid solution and its interface deviate from the ideal state?

In thermodynamics, it is known that residual properties show how much a mixture deviates from the ideal state. Do we have other criteria for this? Do we have any criteria by which we can recognize...
