Density

Density is a measure of how much mass is contained in a given volume. It is a key concept in science and is used to describe the compactness of a substance. The formula for calculating density is:

Density = Mass / Volume

Where:

• Density is measured in units such as grams per cubic centimeter (g/cm³) or kilograms per liter (kg/L)
• Mass is the amount of matter in an object and is typically measured in grams or kilograms
• Volume is the amount of space an object occupies and is typically measured in cubic centimeters (cm³) or liters (L)

Understanding Density

Objects with a high density have a lot of mass in a small volume, while objects with low density have less mass in the same volume. For example, a block of lead has a higher density than a block of wood because the lead block contains more mass in the same volume.

Application of Density

Density is used in various scientific fields, including physics, chemistry, and engineering. It is used to identify substances, determine the purity of materials, and predict the behavior of fluids. Understanding density is crucial for understanding how substances interact with each other and with their environments.

Study Guide

Here are some key points to remember about density:

1. Density is a measure of how much mass is contained in a given volume
2. The formula for density is Density = Mass / Volume
3. Density is typically measured in units such as grams per cubic centimeter (g/cm³) or kilograms per liter (kg/L)
4. Objects with high density have a lot of mass in a small volume, while objects with low density have less mass in the same volume
