Chapter 12, Problem 2RQ

Interpretation Introduction

Interpretation:

Comparison of air pressure inside balloon and outside balloon has to be explained.

Concept Introduction:

Pressure represents force produced by substances per unit area on other substances. Therefore pressure of gas can represent force produced by gas on walls of container. 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 $\left(\text{Pa}\right)$.
