Difference between Surface energy and Surface tension

Surface energy vs. Surface tension

Surface Free energy, or interfacial free energy, quantifies the disruption of intermolecular bonds that occur when a surface is created. Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible.

Similarities between Surface energy and Surface tension

Surface energy and Surface tension have 12 things in common (in Unionpedia): Cohesion (chemistry), Contact angle, Gas constant, Gibbs free energy, Gibbs isotherm, Kelvin equation, Sessile drop technique, Sodium chloride, Solid, Temperature, Vapor pressure, Young–Laplace equation.

Cohesion (chemistry)

Cohesion (from Latin cohaesiō "cling" or "unity") or cohesive attraction or cohesive force is the action or property of like molecules sticking together, being mutually attractive.

Contact angle

The contact angle is the angle, conventionally measured through the liquid, where a liquid–vapor interface meets a solid surface.

Gas constant

The gas constant is also known as the molar, universal, or ideal gas constant, denoted by the symbol or and is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure-volume product, rather than energy per temperature increment per particle.

Gibbs free energy

In thermodynamics, the Gibbs free energy (IUPAC recommended name: Gibbs energy or Gibbs function; also known as free enthalpy to distinguish it from Helmholtz free energy) is a thermodynamic potential that can be used to calculate the maximum of reversible work that may be performed by a thermodynamic system at a constant temperature and pressure (isothermal, isobaric).

Gibbs isotherm

The Gibbs adsorption isotherm for multicomponent systems is an equation used to relate the changes in concentration of a component in contact with a surface with changes in the surface tension, which results in a corresponding change in surface energy.

Kelvin equation

The Kelvin equation describes the change in vapour pressure due to a curved liquid–vapor interface, such as the surface of a droplet.

Sessile drop technique

Fig 1: An illustration of the sessile drop technique with a liquid droplet partially wetting a solid substrate. \theta_C is the contact angle, and \gamma_SG\, \gamma_LG\, \gamma_SL\ represent the solid–gas, gas–liquid, and liquid–solid interfaces, respectively. The sessile drop technique is a method used for the characterization of solid surface energies, and in some cases, aspects of liquid surface energies.

Sodium chloride

Sodium chloride, also known as salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.

Vapor pressure

Vapor pressure or equilibrium vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system.

Young–Laplace equation

In physics, the Young–Laplace equation is a nonlinear partial differential equation that describes the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of surface tension or wall tension, although usage on the latter is only applicable if assuming that the wall is very thin.
