Illinois Field Crop Applicators Practice Test

What is a typical range for the density of most liquids compared to water?

1. 0.5 - 2.0 g/cm³

2. 1.0 - 1.5 g/cm³

3. 0.1 - 0.5 g/cm³

4. 2.0 - 3.0 g/cm³

The correct answer is: 1.0 - 1.5 g/cm³

The correct answer reflects the typical range for the density of liquids in comparison to water, which has a density of approximately 1.0 g/cm³ at standard temperature and pressure. Most liquids fall within the range of 0.5 - 2.0 g/cm³, with many common liquids such as oils, alcohols, and various solvents being found just above or below the density of water. Several liquids can have densities that are higher or lower than water, resulting in a wide variety of values. The range of 1.0 - 1.5 g/cm³ encompasses many dense liquids without reaching extremes that might include gases or light substances. This density range is practical when considering liquids used in agricultural applications, where maintaining a balance in density for proper application and mixing is essential. It's important to note that the other ranges provided do not accurately represent the typical densities of liquids. For instance, lower densities such as 0.1 - 0.5 g/cm³ would generally include lighter substances or gases rather than typical liquids, while the 2.0 - 3.0 g/cm³ range would include much denser liquids that are less common in agricultural scenarios. Thus, the selected range aptly captures the expected density of most
