A scientist collected the following data, which show how the pressure of water vapor changes with temperature.

\begin{tabular}{|c|c|}
\hline Temperature [tex]$\left({ }^{\circ} C \right)$[/tex] & Pressure [tex]$(mm \ Hg)$[/tex] \\
\hline 0 & 4.5 \\
\hline 10 & 9.6 \\
\hline 20 & 19.1 \\
\hline 30 & 33.2 \\
\hline 40 & 58.7 \\
\hline 50 & 95.6 \\
\hline
\end{tabular}

What would a scientist do to best communicate these data to other scientists in a presentation?

A. Replace the table with text highlighting pressures
B. Change the unit of pressure to atm.
C. Make a graph for better visual representation.
D. Display only rows 1, 3, and 6 of the data to simplify results.



Answer :

To best communicate the data showing how the pressure of water vapor changes with temperature to other scientists in a presentation, it is important to choose a method that makes the pattern and relationship between the two variables clear and easily interpretable.

Given the data in the table:

[tex]\[ \begin{array}{|c|c|} \hline \text{Temperature } (^{\circ}C) & \text{Pressure } (mm \text{Hg}) \\ \hline 0 & 4.5 \\ 10 & 9.6 \\ 20 & 19.1 \\ 30 & 33.2 \\ 40 & 58.7 \\ 50 & 95.6 \\ \hline \end{array} \][/tex]

Analyzing the options given:

1. Replace the table with text highlighting pressures: While text can describe the data, it can become cumbersome and difficult to compare the values quickly.

2. Change the unit of pressure to atm: This could help if the audience prefers a different unit of measurement, but it does not necessarily make the relationship between temperature and pressure clearer.

3. Make a graph for better visual representation: This is the best option, as a graph can visually show the trend between temperature and pressure, making it easier for the audience to observe how the pressure increases with temperature. A graph, such as a line graph or scatter plot, can immediately convey the relationship and enable quick interpretation.

4. Display only rows 1,3, and 6 of the data to simplify results: This would lose important information and not adequately represent the trend across all the collected data points.

The most effective method to communicate the data to other scientists would be to make a graph for better visual representation. This method allows the audience to quickly and easily understand the relationship between temperature and pressure.

Thus, the best choice is:

Make a graph for better visual representation.
