wetting tension (work of immersional wetting per unit area)

https://doi.org/10.1351/goldbook.W06674

The work done on a system when the process of immersional wetting involving unit area of phase β is carried out reversibly:

w_{W}^{α β δ} = γ^{β δ} - γ^{α β}

where

γ^{α β}

and

γ^{β δ}

are the surface tensions between two bulk phases α, β and β, δ, respectively.
