If you increase mass while keeping volume constant, what happens to density?

• A. Density increases.
• B. Density decreases.
• C. Density stays the same.
• D. Density is not defined.

Answer: (A)

Density is mass per unit volume. If you keep the volume the same and increase the mass, you’re putting more matter into the same space, so the amount of mass per unit volume goes up. That means density increases. For example, in 1 cubic centimeter, if mass goes from 2 g to 5 g, density goes from 2 g/cm^3 to 5 g/cm^3. The only time density wouldn’t be defined is if the volume were zero, which isn’t the case here.
