AFOQT Practice Test

Which of the following properties can be changed easily?

1. Density

2. Shape

3. Specific Gravity

4. Color

The correct answer is: Shape

The property that can be changed easily is shape. This is because shape is a physical property that can be altered without changing the substance itself. For instance, you can bend, cut, or mold materials into different forms, and these actions do not affect the chemical composition of the material. In contrast, properties like density, specific gravity, and color are more intrinsic to the material and typically require specific conditions or processes to change. Density is determined by the mass and volume of a substance, and altering it usually involves a change in temperature or pressure. Specific gravity, which is a measure of density relative to water, depends directly on the density of the substance and also requires changes in conditions for alteration. Color can change under certain conditions, such as exposure to light or chemical reactions, but these changes are often less straightforward and not as easily executed as simply changing the shape of a material.
