AFOQT Practice Test

What is the primary characteristic of intrinsic properties?

1. They can be altered by external forces

2. They depend on the amount of substance present

3. They do not change based on quantity

4. They relate to the shape of the substance

The correct answer is: They do not change based on quantity

Intrinsic properties are characteristics of a substance that remain constant regardless of the amount of the substance present. These properties are inherent to the material itself and are not influenced by external factors or the size or shape of the sample. For example, density, boiling point, and color are intrinsic properties that remain the same whether you have a small or large piece of a substance. The other options suggest characteristics that are not typical of intrinsic properties. Some characteristics may be altered by external forces or depend on the quantity of the substance, which aligns more with extrinsic or extrinsic properties. Thus, the key feature is the constancy of these properties, making the selected answer correct.
