Density (volumetric mass density or specific mass) is a substance's mass per unit of volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.

2025年3月25日 · Density, mass per unit volume of a substance. The formula for density is d=M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of gram per cubic centimeter. For example, the density of water is 1 gram per cubic centimeter.

2017年12月2日 · Density is the amount of mass in a unit of volume. In a liquid, the portion with the highest density is at the bottom of the container. By definition, density is mass per unit volume .

Density Definition: Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object. Iron, platinum, and lead are examples of dense materials.

2020年2月5日 · Put another way, density is the ratio between mass and volume or mass per unit volume. It is a measure of how much "stuff" an object has in a unit volume (cubic meter or cubic centimeter). Density is essentially a measurement of how tightly matter is crammed together.

2024年8月27日 · Density is a physical property that is defined as a substance’s mass divided by its volume. Density is usually a measured property of a substance, so its numerical value affects the significant …

The meaning of DENSITY is the quality or state of being dense. How to use density in a sentence.

This free density calculator determines any of the three variables in the density equation given the other two.

2023年9月20日 · The formula for calculating density is ρ = m/V, where p is the density, m is the mass and V is the volume. Density (p) is equal to mass (m) divided by volume (V).

Density (\rho) (ρ) is the amount of mass (m) (m) per unit volume (V) (V) of a substance. \rho = \frac {m} {V} ρ = V m. Density is an intensive property, which means the density does not change as the amount of the substance present changes.
