Two fluids are immiscible if they retain a distinct phase identity when they are mixed. As a consequence of the different degrees of attraction between molecules of a different nature a tension exists at the interface, which is called surface tension. The surface tension σ has the dimension of a force per unit length of the interface edge (Figure C7).
