Chapter 12, Problem 2PE

Interpretation Introduction

Interpretation:

Blank values in table below have to be determined.

$\begin{array}{llll}\hfill & \text{mm Hg}\hfill & \text{lb/in}{\text{.}}^2\hfill & \text{atm}\hfill \\ \left(\text{a}\right)\hfill & 789\hfill & \hfill & \hfill \\ \left(\text{b}\right)\hfill & \hfill & 32\hfill & \hfill \\ \left(\text{c}\right)\hfill & \hfill & \hfill & 1.4\hfill \end{array}$

Concept Introduction:

Barometer is used for measurement of pressure of gas in atmospheric units $\left(\text{atm}\right)$. Pressure can also be represented in many units such as $\text{torr}$, $\text{mm Hg}$, and pascal $\left(\text{Pa}\right)$. These units can be related to one another as follows:

  $\begin{array}{c}1\text{ atm}=760\text{ torr}\\ =760\text{ mm Hg}\\ =\text{101325 Pa}\\ =\text{101}\text{.325 kPa}\\ =14.7\text{ lb/in}{\text{.}}^2\end{array}$
