Surface Energy

1. What is meant by Surface Energy?

Surface Energy is the work done per unit area by the force that creates the new surface.

2. What is the Formula of Surface Energy?

The formula of surface energy is Energy/Area. It can be also expressed as

Surface Energy = Energy × [Area]^-1

3. What is the Unit of Surface Energy?

SI unit for measuring Surface Energy is N/m.

4. What are Examples of Surface Energy?

Glasses, Ceramics, Metals, and various other materials are held together by stronger bonds which are examples of surface energy.

5. What is the Dimensions of Surface Energy?

Dimensions of Surface Energy is [MT^{– 2}].

6. What is Relationship Between Surface Tension and Surface Energy?

The relation between Surface Tension and Surface Energy is given by,

Surface Energy = Surface Tension

7. What is Surface Free Energy?

Surface Free Energy is defined as the work done required to increase the surface area of the solid phase. Surface Free Energy affects the wettability of the solid.

Surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created.  It is also called surface-free energy or interfacial-free energy. In simple language, surface energy can be defined as the work per unit area done by the force that creates the new surface.

Surface energy is the energy that exists between the surface molecules of solid materials or substances when a comparable attractive force exists. The Ratio of Surface Energy to the Surface Area is known as Surface Tension. Low to high energies, or vice versa, are different. It is impossible to measure surface energy. It occurs as a result of a molecule-molecule interaction. A stretched membrane refers to the free surface of a liquid. The surface, which is known as surface-free energy, holds some Potential Energy on the liquid surface. Surface energy will be discussed in detail in this article.
