Understanding Density
Density is defined as the mass of an object divided by its volume. It is a physical property that helps identify substances and understand their behavior in different states of matter. The formula for density is expressed as:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
Where:
- Mass is measured in grams (g)
- Volume is measured in cubic centimeters (cm³) or liters (L)
Understanding density is crucial for various scientific applications, including buoyancy, material selection in engineering, and chemical reactions.
