Therefore pentane pentane will have the weakest surface tension, followed by hexane, octane and lastly decane. Pentanol is an alcohol. Alcohols have greater surface tensions than the alkanes due to the -OH group which introduces hydrogen bonding. Therefore it will have the greatest surface tension. REFERENCE

What is the Difference Between Surface Tension and Surface Energy

The attractive force of the molecules present at the surface of a liquid towards each other is called the surface tension of that liquid. Surface energy is the equivalent attractive force present between the molecules at the surface of a solid substance. This attractive force is what holds a substance together into a cohesive form.

Why is the surface tension of water higher than that of ethanol?

That is, they stick close together well, and thus, are hard to break apart. As a result, it is more difficult to deform the surface of water than the surface of ethyl alcohol. Therefore, since water molecules on a liquid surface are harder to push down on the surface tension is higher for water than for ethyl alcohol. Answer link

Why is the surface tension of Ethanol higher than that of … – Quora

Answer (1 of 3): The surface tension in ethanol is caused by the intermolecular force of hydrogen bonding between the ethanol molecules. That’s quite effective, since the organic part of the molecule is relatively small and the polar (alcohol group) part is at the end of the molecule. Image cour…

Surface Tension – an overview | ScienceDirect Topics

More specifically, the surface tension is a measure of the surface free energy of liquids, i.e., the extent of energy stored at the surface of liquids. Although it is also known as interfacial force or interfacial tension, the name surface tension is usually used in systems where the liquid is in contact with gas. Qualitatively, it is described …

pentanol surface tension – michaelsphotog.com

Though I have certainly paid lip service to this property in the past, I had never really thought about having students quantify this in any way. Eventually, the gap becomes too large and the stretched out liquid snaps back. Additionally, there were only a few liquids I had immediate access to or felt comfortable with letting my students use (ex: water and alcohol) that could easily …

Why does isopropanol have a higher surface tension than water?

Answer: Oh, but it doesn’t! Water has a high surface tension (72 dyne/cm), while isopropanol is about 21 dyne/cm. Most organic liquids have quite low surface tensions, because the atoms on the outside of the molecules (usually hydrogens) don’t have strong hydrogen bonding capability. Isopropanol…

What are Surfactants and How Do They Impact Surface Tension?

A surfactant, at its most basic, is a substance that is designed to reduce the surface tension of a liquid. For many operations in manufacturing processes, it is necessary for a liquid to spread out and wet a surface. Adding a surfactant to a coating or detergent lowers the surface tension of the liquid so it will flow more, covering the …

Cohesion and Surface Tension | sciphile.org

mercury. 0.465 3. Surface tension tends to reduce with increasing temperature. As a liquid heats up, the molecules in it speed up, which tends to break the bonds produced by cohesive forces. Table 2 shows the effect of temperature on the surface tension of water. The colder the water, the higher the surface tension.

Surface Tension Basics – Lesson – TeachEngineering

Droplets form due to the surface tension of the liquid—a larger surface area requires more energy to maintain due to the molecular forces associated with surface tension. When water transitions from a column into droplets, the same volume of water has a smaller surface area and therefore requires less energy.
