Question

what is the meaning of surface energy ​

Answer 1

Answer:

Liquids will often have lower surface energies than solids (due to the weak forces interacting between molecules), which is why liquids usually spread out. Surface energy can be defined as the energy required per unit area to increase the size of the surface, and as such is often quoted in units of mN/m.
