Density is defined as which of the following?

Density is defined as which of the following?

• A. The amount of matter in an object divided by its volume
• B. The weight of an object
• C. The color intensity of a substance
• D. The energy stored in bonds

Answer: (A)

Density tells you how much matter is packed into a given volume. It is found by dividing the mass of an object by its volume, so density = mass / volume. Mass is the amount of matter, and volume is the space the object occupies. If the same mass takes up less space, density is higher; if it takes more space, density is lower. For example, a metal block has a lot of mass in a small volume and feels dense, while a piece of wood or a balloon of the same size has less mass in the same space, so it’s less dense. The weight of an object is the gravitational pull on its mass, which can vary with location; color intensity and energy stored in bonds describe other properties, not density.
