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

Explanation:

• Density is defined as mass per unit volume. The formula for density is \(

ho=\frac{m}{V}\), where \(
ho\) is density, \(m\) is mass, and \(V\) is volume.

• "Height of a point above sea level" refers to altitude.
• "Force pushing on an area or a surface" is pressure (\(P = \frac{F}{A}\), where \(P\) is pressure, \(F\) is force, and \(A\) is area).
• "Amount of matter an object contains" is mass.

Answer:

amount of mass in a certain volume
