Surface Tension of Water and Breaking through that surface tension ...

WebMar 11, 2013 · This lower surface tension has two direct effects when it comes to the paper ball. First, the lower surface tension means that the paper can’t sit atop the water’s surface, allowing more of the water to come in contact with more of the paper. Second, the weakened hydrogen bonds mean that the water is more likely to soak into the porous ... WebThe cohesive forces between the water molecules are very strong making the surface tension of water high. As surfactants absorb they break these interactions.
