Question

define surface energy and surface tenssion​

Answer 1

Answer:

Surface tension & surface energy

A volume phase is a region without erratic changes in physical parameters. Contact between two different phases gives rise to a phase boundary. The contact area is called interface. There are five different types of interfaces: solid-solid, solid-liquid, solid-gaseous, liquid-liquid and liquid-gaseous (there is no gaseous-gaseous interface because all gases are miscible). The term surface is usually used for solid-gaseous and liquid-gaseous interfaces.

Note that even though the term interface suggests a sharp two dimensional boundary with an instantaneous change of the physical parameters, one finds in real systems, especially in the liquid-gaseous case, a three dimensional region in which the parameters change continuously (see figure 1). However the simplified assumption of a sharp interface is sufficient when coping with macroscopic interfacial phenomena.

Answer 2

Answer:

surface energy:

Surface energy can be defined as the energy required per unit area to increase the size of the surface.

surface tenssion:

Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible.
