Which of the following best describes the concept of density without using its mathematical formula?

• A. Density is the amount of space a substance occupies.
• B. Density is the temperature at which a substance changes state.
• C. Density is the total mass of a substance regardless of its volume.
• D. Density is a measure of how much mass is contained in a given volume of a substance.

Answer: (D)

Verified step by step guidance

1. Understand that density is a physical property that relates the mass of a substance to the space it occupies, which is its volume.
2. Recognize that density describes how tightly matter is packed within a certain volume, rather than just the amount of space or the total mass alone.
3. Eliminate options that describe unrelated concepts, such as temperature of state changes or just the total mass without considering volume.
4. Focus on the idea that density is about the ratio or relationship between mass and volume, indicating how much mass is contained in a specific volume.
5. Conclude that the best description of density is that it measures how much mass is contained in a given volume of a substance, without directly using the formula.
