Answer to Question #119914 in General Chemistry for Brittney

Question

Why the properties of the molecules forming the interface are different from those in the bulk. Explain the reason (6mks)

Answer 1

An interface is a border between two or more phases existing together.

Molecules in the liquid interface are only attracted by cohesive forces with more liquid molecules which are located adjacent to or just below them.They can also create adhesive forces of attraction with molecules of other phases in the interface.

In bulk, molecules are surrounded by other molecules in all directions that have equal force of attraction.
