Study Notes
Surface Energy Units
- Surface energy is measured in Joules per square meter (J/m²).
- This unit reflects the energy required to create a new surface area.
- An alternative unit for surface energy is ergs per square centimeter (erg/cm²).
Surface Energy Dimensions
- The dimension of surface energy is [M L¹ T⁻²].
- This translates to mass (M), length (L), and time (T).
Surface Energy and Related Quantities
- Surface tension is directly related to surface energy.
- Intermolecular forces play a crucial role in determining surface energy.
- Wettability is a phenomenon influenced by surface energy.
High Surface Energy
- A high surface energy indicates a material's strong attraction between molecules.
- This results in a tendency to minimize surface area, leading to phenomena like capillary action and cohesion.
