What are the examples of substances with high viscosity?

Viscosity is the property of a fluid that describes how easily it flows. Fluids with high viscosity flow slowly, while fluids with low viscosity flow more easily.

For example, when comparing water and honey:

• Water flows quickly because it has low viscosity.
• Honey flows slowly because it is thicker and has high viscosity.

In simple terms, viscosity refers to the thickness or resistance to flow of a liquid. It can be measured using an instrument called a viscometer.

In organic liquids, those with longer carbon chains generally have higher viscosity. The SI unit of viscosity is the pascal-second (Pa·s).

Examples of high-viscosity substances:

• Honey
• Glue
• Peanut butter
• Ketchup
• Long-chain hydrocarbons
