Hello sadaf,

Great questions! The interface is a chemical term for the place where two dissimilar chemicals meet - this is a common term used in surfactants (surface-active materials).

The interfacial area is that physical area (calculated or measured) where the individual area of two different materials are calculated. A similar area  is discribed with surface tension http://en.wikipedia.org/wiki/Surface_tension.

If you have a mixture of alot of water with a little bit of oil - the water is the continuous phase (more of it) and the oil is the dispersed phase (non-continuous phase). More on the continuous phase is shown in the following link: http://en.wikipedia.org/wiki/Emulsion.

I hope this helps.

Sincerely,

Eugene
