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

| Temperature (°C) | Pressure (mm Hg) |
|------------------|------------------|
| 0 | 4.5 |
| 10 | 9.6 |
| 20 | 19.1 |
| 30 | 33.2 |
| 40 | 58.7 |
| 50 | 95.6 |

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 these data to other scientists in a presentation, the scientist should:

Make a graph for better visual representation

Here’s a detailed reasoning for this solution:

Graphs such as line graphs or scatter plots are excellent tools for visually representing the relationship between two variables. In this case, plotting the temperature on the x-axis and the pressure on the y-axis will help other scientists quickly understand the trend and pattern of how pressure changes with temperature. It will make it easier to see the relationship at a glance compared to reading through rows of numeric data in a table.

1. Line Graph/Scatter Plot: By creating a graph, you allow the audience to quickly grasp how pressure increases as temperature increases. Visually, it’s much faster and more intuitive for the mind to recognize patterns and trends rather than parsing through a table of numbers.

2. Clarity and Impact: A graph can clearly show whether the relationship is linear, exponential, or follows another trend. It can also highlight any anomalies or outliers in the data that might be missed in a table format.

3. Engagement: During presentations, visual aids such as graphs keep the audience engaged and can serve as a focal point of discussion. They help in communicating complex data succinctly and effectively.

Therefore, the best course of action to communicate the data effectively is to make a graph for better visual representation.
