Density measures how much mass is contained in a given volume, or more generally, how closely packed things are. In physics, it's calculated as mass divided by volume. It's also used to describe population density (how many people per area) or the thickness of materials like hair or fog.
Density 测量给定体积中包含多少质量,或更一般地说,事物有多紧密。在物理学中,它的计算方法是质量除以体积。它也用于描述人口密度(每个区域有多少人)或头发或雾等材料的厚度。
Density mide cuánta masa está contenida en un volumen dado, o más generalmente, qué tan apretadas están las cosas. En física, se calcula como masa dividida por volumen. También se usa para describir la densidad de población (cuántas personas por área) o el grosor de materiales como el cabello o la niebla.
Densityは、特定の体積にどれだけの質量が含まれているか、またはより一般的に、物がどれだけ密集しているかを測定します。物理学では、質量を体積で割って計算されます。人口密度(面積あたりの人数)や、髪の毛や霧などの材料の厚さを表すためにも使用されます。
밀도는 주어진 부피에 얼마나 많은 질량이 포함되어 있는지, 또는 더 일반적으로 사물이 얼마나 빽빽하게 모여 있는지를 측정합니다. 물리학에서는 질량을 부피로 나누어 계산합니다. 인구 밀도(면적당 인구수)나 머리카락, 안개 등의 농도를 설명할 때도 사용됩니다.
