Question 126

What is the difference between "thickness" and viscosity? Is viscosity just a fancy word for thickness?
Viscosity is a measurable quantity—a liquid has a specific viscosity as measured in units of poise or pascal-seconds. Thickness refers to the same characteristic as viscosity, but isn't a specific quantity. It's certainly correct to say that a thick liquid is a liquid with a large viscosity.
