Question

What effect does capillary action have on the reading of a manometer with uniform diameter?

a) Increases accuracy.
b) Decreases accuracy.
c) No effect on accuracy.
d) Depends on the fluid type.

Answer 1

Capillary action increases the accuracy of a manometer with uniform diameter.

Step-by-step explanation:

Capillary action refers to the ability of a liquid to rise or fall in a narrow tube due to the forces of surface tension, cohesion, and adhesion. In the context of a manometer with uniform diameter, capillary action can affect the reading of the manometer by increasing accuracy.

This is because capillary action allows for a more precise measurement of the height of a liquid column due to the smaller tube diameter, resulting in a more accurate reading.
