# Viscosities surface tension and liquid viscosity

Therefore, the viscosity is big. Surface Tension and Temperature As the temperature of a liquid increases, its surface tension decreases. The two most common methods for evaluating the viscosity of a liquid are 1 to measure the time it takes for a quantity of liquid to flow through a narrow vertical tube and 2 to measure the time it takes steel balls to fall through a given volume of the liquid.

From the strength of this interaction, predict the behavior of the oil and the shape of the meniscus.

Since the particles have more kinetic energy, they move more rapidly, which weakens the intermolecular force attractions in liquids. Vinegar only has dipole-dipole forces and London dispersion forces; therefore, it supports the least mass.

This graph summarizes all the previous relationship between Surface Tension and Viscosityfor all liquids. My hypothesis, for my science fair project, is that as temperature increases, viscosity and surface tension both decrease. The meniscus will be concave. If I were to do the project again, in my opinion, it would not change.

Even though, particles in the vinegar move more rapidly with increasing temperature, there are still dipole-dipole forces in the vinegar.

Liquids like honey have a higher viscosity because they contain more complex molecular structures; while water consists of simple hydrogen and oxygen bonds, honey also contains sugars.

The viscosities of some representative liquids are listed in Table Even though the dipole-dipole forces of vinegar decrease with increasing temperatures, the curve of vinegar is less steep than the curve of water, because the density of vinegar is larger than that of water.

I calculate the equations of Surface tension vs. Fluids and nutrients are transported up the stems of plants or the trunks of trees by capillary action.

When a glass capillary is is placed in liquid water, water rises up into the capillary.

This is the reason that milk supports the most mass at higher temperatures. Because fat is polar molecule, there are dipole-dipole forces in milk.

Water has both strong adhesion to glass, which contains polar SiOH groups, and strong intermolecular cohesion.Viscosity and surface tension are two physical characteristics of a liquid.

Viscosity is the measure of how resistant to flow a liquid is, while surface tension is defined as how resistant the surface of a liquid is to penetration. Surface tension, capillary action, and viscosity are unique properties of liquids that depend on the nature of intermolecular interactions.

Surface tension is. Apr 01,  · Since viscosity and surface tension are both properties of liquid, there is a relationship between them that surface tension varies directly as viscosity with temperature being constant.

Viscosity Boil water in the electrical kettle.4/5(71). Oct 11,  · Compared to Viscosity, Surface Tension is a simpler phenomenon. It is basically stable, changed mostly by temperature and chemicals that modify the bonding characteristics of the molecules.

Learn about viscosity & surface tension, units of measurement with Byju's. My report is dealing with liquid viscosity and how they are used to help us measure liquids and gives us the accurate temperature that we have today.

Densities, viscosities, and surface tension have been measured as a function of composition for the binary liquid mixture of diethylene glycol diethyl ether + water at K under atmospheric pressure. Densities were determined using a capillary pycnometer.

Viscosities were measured with a Ubbelohde capillary viscometer. .
