Which quantity describes how tightly packed matter is inside of an object?
The quantity that describes how tightly packed matter is inside an object is called density. Density is the mass of an object per unit volume, and it determines how closely particles are packed together within the object.
The quantity that describes how tightly packed matter is inside of an object is called density. Density is defined as the amount of mass per unit volume. In simpler terms, it tells us how much matter is "packed" into a given amount of space. The equation for density is:
Density = Mass / Volume
To determine the density of an object, you need to know its mass and volume.
To measure the mass of an object, you can use a balance or a scale. Place the object on the balance or scale and record the reading in units of mass (such as grams or kilograms).
To determine the volume of a regular-shaped object (such as a cube or a sphere), you can measure the dimensions of the object (length, width, and height) and use a relevant formula to calculate the volume. For example, the volume of a cube is calculated by multiplying the length, width, and height. For irregular-shaped objects, you can use a displacement method by immersing the object in a known volume of liquid and measuring the increase in volume.
Once you have the mass and volume of the object, you can divide the mass by the volume to find the density.
It's important to note that density is a fundamental property of matter and is often used to identify substances or compare different materials.
