Chapter 2.4, Problem 56SSC

Interpretation Introduction

Interpretation:

A circle graph needs to be drawn for the composition of air: $78.08\%\text{N}$, y $\text{20}\text{.95\%}{\text{O}}_{\text{2}}$, $\text{0}\text{.93\%}\text{Ar}$ and $\text{0}\text{.04\%}{\text{CO}}_{\text{2}}$ and other gases.

Concept introduction:

The difference and trend in the data can be easily visualized via plotting graphs. This can be said that a visual display of data is its graph. There are three types of graphs:

• The parts of a fixed whole can be represented by a circle graph. The different parts are represented as percents where the entire circle represents $100\%$.
• The variation of a quantity across different categories can be represented by a bar graph.
• In the line graph, the intersection of data for two variables is represented by the different points.

Answer to Problem 56SSC

A circle graph showing the composition of air as follows:

Explanation of Solution

Graphs visually depict data by making it easier to see the different and trends. The parts of a fixed whole can be represented by a circle graph. The different parts are represented as percents where the entire circle represents $100\%$.

A circle graph showing the composition of air as follows:

Conclusion

A circle graph showing the composition of air as follows:
