tensiunea superficială și unghiul de contact sunt ambele mărimi care descriu proprietățile unui lichid pe o suprafață solidă,
but there are some differences between them.
Surface tension refers to the interaction between molecules on the surface of a liquid.
These forces enable molecules on the surface to form a tightly bonded layer on the surface,
making the liquid surface form a relatively stable interface.
The amount of surface tension determines whether the liquid surface can form a concave shape...
