Mesurment of surface tension and interfacial tension
Answers
Answer:
The main difference between these two is the places where it occurs. Surface tension is defined to a single liquid surface, whereas the interfacial tension is defined to the interface of two immiscible liquids.
Interfacial tension has the units mN/m and is designated by the symbol σ or γ.
Surface tension is what allows a denser object, such as an insect, to be able to float on the water's surface. Surface tension is measured by the amount of force (N) exerted on a unit such as length (m) or the amount of energy of a measured area. These are measured as Newton per meter (or N/meter).

Answer:
The measurement of the surface and interfacial tension can be done by using Sigma force tensiometer. It is based on the force measurements of the interaction of a probe at the liquid-gas or liquid-liquid interface. A probe is hang on the balance and brought into contact with the liquid interface tested.
