A liquid can change its shape depending on the container it is poured into and depending on extreme temperature change, gases fill in and spread to fill the space they can reach and a solid does not change its shape but we can change its shape by either bending it, taking away from it or melting it..

A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.

The forces between liquid particles are weaker than the forces between solid particles. This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.

Liquids are non-compressible and have constant volume but can change shape. A liquid’s shape is dictated by the shape of the container it is in. Gases do not have a constant volume or shape; they not only take the shape of the container they are in, they try to fill the entire container.

Summary: Physicists surprised to find that in specially coated tubes, the more viscous a liquid is, the faster it flows. It’s widely known that thick, viscous liquids — like honey — flow more slowly than low-viscosity liquids, like water.

Water, gasoline, and other liquids that flow freely have a low viscosity. Honey, syrup, motor oil, and other liquids that do not flow freely, like those shown in Figure 1, have higher viscosities.

It is commonly perceived as “thickness”, or resistance to pouring. Viscosity describes a fluid’s internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is “thin”, having a low viscosity, while vegetable oil is “thick” having a high viscosity.

Everything I have come across that is low viscosity is inflammable – acetone, ether, silicone oil, fuel, etc. I have found some confusing things in my research. Acetone has a viscosity 3x less than water but weighs 2.5 times more.

What factors affect viscosity? Viscosity is resistance to flow. For liquids, typically the larger the intermolecular forces (IMF) the higher the viscosity. The other factors that affect viscosity are temperature and the shape of the molecule.

3.2 FACTORS AFFECTING VISCOSITY The viscosity of Newtonian fluids is affected by temperature, pressure, and, in the case of solutions and mixtures, by composition.

The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced.

When the inter-molecular forces of attraction are strong within a liquid, there is a viscosity. Cohesive forces are attractive forces exist between molecules of the same substance. So, cohesive forces are the main cause of viscosity.

‘drop’) is one of the most common methods for measuring surface tension. The principle is to measure the weight of drops of a fluid of interest falling from a capillary glass tube, and thereby calculate the surface tension of the fluid. From it we can determine the surface tension.

Viscosity generally increases as the temperature decreases. The viscosity of a liquid is related to the ease with which the molecules can move with respect to one another. Thus the viscosity of a liquid depends on the: strength of attractive forces between molecules, which depend on their composition, size, and shape.

Xanthan gum, Glycerin, CMC, and Carbopol are different materials for increasing the viscosity of water.

Viscosity is a measure of an oil’s resistance to flow. It decreases (thins) with increasing temperature and increases (or thickens) with decreased temperature. A general increase in viscosity at higher temperatures, which results in lower oil consumption and less wear.

Smaller molecules slide past each other more easily than larger molecules do. Larger molecules also have stronger intermolecular forces, such as London Forces, which connect them to one another with greater power. This inhibits molecular flow, resulting in higher viscosity.
