define surface energy
Answers
Answer:
*Answer*
The surface energy may therefore be defined as the excess energy at the surface of a material compared to the bulk, or it is the work required to build an area of a particular surface. Another way to view the surface energy is to relate it to the work required to cut a bulk sample, creating two surfaces.

Answer:
In the bulk form of a material, atoms are generally stable and have a balanced set of bonds/interactions. In contrast, the surface atoms will have an incomplete, unbalanced set of interactions, and therefore have unrealised bonding energy. ‘Surface energy’ is a relative measurement of the energy at the surface (which is a result of this incomplete bonding). It is positively correlated to the strength of bulk interactions and the level of surface exposure. Therefore, surface energy will be higher if the bulk interactions are stronger, or if the surface exposure is greater.
