Surface tension of a mixture

WebApr 8, 2024 · The calculated results indicated that the surface tension of liquid Fe-3.0%Si alloys decreased with the increase of B content from 0.5% to 2%, which is in good agreement with the measured results. Si and B with lower surface tension tend to aggregate on the surface of the liquid alloy, while Fe with higher surface tension tends to aggregate ... Webmolecules in the droplet are held together by surface tension while they are in contact with the desk. Other examples of surface tension include water striders, dew drops, raindrops on a window, and soap bubbles! Today, we will examine surface tension by placing drops of different mixtures onto pennies.
