What causes viscosity?

If you want determine viscosity in a liquid, try a simple science experiment by measuring the speed of a metal ball dropped in a container of liquid. The velocity of the ball, combined with the relative densities of the ball and the liquid, can be used to calculate the viscosity of liquids.

Q. What is viscosity in chemistry practical?

Viscosity is another type of bulk property defined as a liquid’s resistance to flow. When the intermolecular forces of attraction are strong within a liquid, there is a larger viscosity. An example of this phenomenon is imagining a race between two liquids down a windshield.

Q. How do you find the viscosity of a liquid experimentally?

If you want determine viscosity in a liquid, try a simple science experiment by measuring the speed of a metal ball dropped in a container of liquid. The velocity of the ball, combined with the relative densities of the ball and the liquid, can be used to calculate the viscosity of liquids.

You can measure the viscosity of a liquid by measuring the velocity of a sphere as it falls through the liquid. The velocity of the sphere, combined with the relative densities of the sphere and the liquid, can be used to calculate the viscosity of the liquid.

Q. How do you explain viscosity to a child?

Viscosity is the property of a liquid that describes how fast or slowly it will flow. You can think of viscosity as how thick a liquid is. A liquid with high viscosity – that is thick, like peanut butter – will flow slowly.

Q. What is viscosity and example?

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of “thickness”: for example, syrup has a higher viscosity than water. A fluid with a high viscosity, such as pitch, may appear to be a solid.

Q. How does viscosity affect a substance?

One can imagine the strength with which the molecules cling together, which will be proportional to the friction. This strength is known as viscosity. Viscosity determines the friction amount, which determines the amount of energy absorbed by the flow.

Is viscosity a physical or chemical property?

Any characteristic of a material that you can observe without changing the identity of the substance is a physical property. Some examples of physical properties are boiling point, melting point, viscosity, density, hardness, malleability, solubility, shape, size, and color.

What is the aim of the viscosity experiment?

The purpose of this experiment is to measure the viscosity of unknown oil with a falling ball viscometer. The principle of the viscometer is to determine the falling time of a sphere with known density and diameter within a fluid filled inside glass tube.

Q. What is the purpose of viscosity experiment?

To measure the viscosity of a sample liquid. Introduction: Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress.

Viscosity is a measure of the resistance of a fluid towards being deformed when under shear stress. Hence, it is also known as shear viscosity. It is caused by the attractive forces between molecules in close contact, and the friction between molecular chains.

Q. 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.
