Question

Which phrase describes density?

-height of a point above sea level
-force pushing on an area or a surface
-amount of mass in a certain volume
-amount of matter an object contains

Answer 1

Density is the amount of mass in a certain volume, mathematically defined as ρ = m/V, and is a key physical property of substances.

Step-by-step explanation:

The phrase that describes density is the amount of mass in a certain volume. Density is a fundamental physical property of substances and is defined as the mass per unit volume. In mathematical terms, density (ρ) is expressed as ρ = m/V, where 'm' represents mass, 'V' represents volume, and ρ (rho) is the symbol for density. It is important for various applications, such as determining whether an object will sink or float in a fluid.
