WebAt this point the force recorded by the balance is used to determine the surface tension according to the equation: ΔF = 2γ (t + w) (1) where ΔF is the net wetting force, 2 (t + w) is the wetted perimeter of the probe, and γ is the surface tension. Note that the contact angle between the plate and the liquid is assumed to be zero. Webhigher surface-tension, which, on mixing with the paraffin, increases its surface-tension, should tend to prevent creeping.
