Question

A change in which of the following characteristics of a solid will result in a change in its density?

• A. Shape of the solid
• B. Size of the solid
• C. Both shape and size of the solid
• D. Neither shape nor size of the solid

Answer 1

The correct option is D Neither shape nor size of the solid

The density of a substance does not change with any change in its shape or size. This is because a change in either of them does not bring about a change in the ratio of mass and volume of the body.
$Density=\frac{Mass}{Volume}$Therefore, density of any body can only be changed by a change in the mass of the body when the volume is unchanged, or by a change in the volume of the body when the mass is unchanged.
