Methyl alcohol, ethyl alcohol, and isopropyl alcohol are free-flowing liquids with fruity odours. Aluminium oxide nanoparticles were purchased from the "Plasmotherm" company, Moscow. In contrast, oils have few, if any, hydrogen bonds amongst their large, organic molecules. Each of the first three substances can form hydrogen-bonds. Surface tension disinfectants (disinfectants are solutions of low surface tension). There is only one liquid having higher surface tension and thats mercury which is a liquid metal with a surface tension of almost 500 mN/m.

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another. Explain that alcohol molecules dont have a structure that is as good as waters for attraction to itself. Surface Tension Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. In order to make this as fair a test as possible, students should place each liquid on two similar pennies that are either both heads or tails. They should also be sure to add single drops of each liquid slowly and carefully. This is due to the fact that increased temperature decreases the cohesive forces between the molecules. That is, they stick close together well, and thus, are hard to break apart. endobj
However, the fairly soluble solutes increase the surface tension of the liquid. Does rubbing alcohol dry faster than water? Rubbing alcohol molecules (2-propanol) are significantly larger than those of water, so their greater London forces result in a higher viscosity.
