Question

____ tells us how closely packed the matter is in an object.

Answer 1

1. Density is a derived quantity from mass and volume is a measure of close package of matter in an object, its given $\mathrm{density}=\frac{\mathrm{mass}}{\mathrm{volume}}$
2. If the matter is closely packed its a heavier object while loosely packed is lighter object.
3. Hence Density tells us how closely packed the matter is in an object.

Hence, Density tells us how closely packed the matter is in an object.
