Relation between surface tension and Surface energy?
Surface energy is numerically equal to surface tension. (but give derivation)
Surface tension is the property of a liquid which resists deformation of its surface. A surface exerts a force outward and perpendicular to the surface when it is being deformed. The surface tension is the energy per unit area necessary to create a larger surface area of a liquid. The cause of surface tension is the cohesive (polar) forces between molecules in the liquid.

Buoyancy is the force exerted by the weight of water displaced by an object that is at least partially submerged in the water. Surface tension a force of attraction exerted between water molecules at the waters surface interface. Something can not become submerged in the water until this surface tension is broken. Surface tension is a very weak force and can be overcome physically or by changing the chemistry at the surface (adding a wetting…
It is to do with surface tension. Water has a certain surface tension caused by the bonding between water molecules. This surface tension can be observed when we see dust floating on the surface of water rather than sinking or small insects skipping across the surface of water. Bubbles of air have to overcome the surface tension to exist. Generally, water bubbles do not last as the water molecules get pulled back to the surface…
yes The presence of impurities either on the surface or dissolved in it, affect surface tension of the liquid. Highly soluble substances increase the surface tension of water, whereas sparingly soluble substances reduce the surface tension of water. The surface tension of a liquid decreases with increase in temperature. The surface tension of a liquid becomes zero at its boiling point and vanishes at critical temperature.
Surface tension is the elasticlike force existing in the surface of a body or a liquid, tending to minimize the area of the surface, caused by asymmetries in the intermolecular forces between surface molecules and viscosity is defined as the property of a fluid that resists the force tending to cause the fluid to flow or the measure of the extent to which a fluid possesses this property.
