Answer to Question 1

Emulsifying or foaming agents contain both polar and nonpolar groups and are drawn to the interface of the two phases to coat the surface of the dispersed droplets. The polar groups are attracted to water, whereas the nonpolar groups are attracted to oil. The emulsifying or foaming agent decreases the surface tension of one liquid more than the other, allowing it to spread and form the dispersion medium.
