If the surface is between two liquids, then the strain between the surface is called ?

Hint:Surface water is any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks. The ocean, despite being saltwater, is additionally considered surface water.

Complete answer:
Interfacial tension is defined because the tendency where an interface becomes spherical to form its surface energy as low as possible. Interfacial tension plays a crucial role in several processes and that they are:
-Emulsions and emulsion ability.
-Quality testing of hydrophobic liquids.
-Solid-liquid phase gets suffering from the interfacial surface tension on a long-term.

Difference between physical phenomenon and interfacial surface tension.
-Surface tension is defined because of the amount of energy which is required for increasing the area between the liquid and gas. Whereas interfacial surface tension is defined because the amount of energy which is required to extend the interfacial area between the two immiscible liquids.
-Separation of oil and water (in this case, water and liquid wax) is caused by a tension within the surface between dissimilar liquids. This sort of physical phenomenon is named "interface tension", but its chemistry is the same.

Note: Physical phenomenon is that the property of the liquid in touch with gas phase (usually air). Interfacial surface tension , on the opposite hand, is the property between any two substances. It might be liquid-liquid, liquid-solid or solid-air.
