A scientist collected the following data, which show how the pressure of water vapor changes with temperature.Temperature (°C)Pressure (mm Hg)04.5109.62019.1 30 33.24058.75095.6What would a scientist do to best communicate these data to other scientists in a presentation?

A graph would make the relationship between temperature and water-vapor pressure easy to see. Plotting the data points—from 0°C and 4.5 mm Hg up to 50°C and 95.6 mm Hg—would clearly show that pressure increases as temperature rises. Changing units or omitting data would not communicate the full pattern as effectively.
