Question

A cone and plate viscometer consists of a cone with a very small angle. What is the purpose of the cone in the viscometer?

1) To measure the viscosity of liquids
2) To measure the temperature of liquids
3) To measure the density of liquids
4) To measure the pH of liquids

Answer 1

The cone in a cone and plate viscometer is used to measure the viscosity of liquids.

Step-by-step explanation:

The purpose of the cone in a cone and plate viscometer is to measure the viscosity of liquids. The cone has a very small angle, which allows for precise measurement of how quickly the liquid flows down the cone. By measuring the time it takes for the liquid to flow through a narrow vertical tube or for steel balls to fall through the liquid, the viscometer can calculate the viscosity of the liquid using Stokes' law.
