Chapter 5, Problem 23Q

Interpretation Introduction

Interpretation:

The level of column of barometer if the barometer is filled with water instead of mercury should be determined and explained.

Concept Introduction:

• The manometer is a devise used measure the pressure of a gas. The pressure of gas is determined by the value of ‘h’ shown by the manometer. This ‘h’-value is added or subtracted with atmospheric pressure to determine the pressure of gas.
• The fluid used in a manometer can be varied.
• The pressure is directly proportional to the mass of fluid, because pressure is the force acting per area.
• Equation for density is,

$\text{Density}\text{=}\frac{\text{Mass}}{\text{Volume}}$
