Following are the factors affectingsurface tention:= *Impurities present in a liquid appreciably affect surface tension. read more
Surface Tension= work done on liquid/ change in area Or Surface Tension= Force / Length Now the two (and one for free) factors affecting surface tension are as follows: Temperature; Viscosity; Nature of the surface in contact with liquid. read more
The surface tension characteristics of a fluidic substance stay basically stable, but can be changed by temperature variations, chemicals that modify the bonding characteristics of the molecules, oxidation and the presence of impurities. Let’s consider the effects of these four conditions on surface tension: Temperature. As temperature decreases, surface tension increases. read more
First of all, surface tension depends on the temperature, composition, and pressure. For anti-foam effect, reducing surface tension does not always correspond to ani-foam. As an example, SDS has low values of surface tension (about 28 mN/m at its CMC), but it is a highly foaming agent. read more
