1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It's an intensive property, meaning it doesn't depend on the amount of material.

2. How to Calculate Density

The density formula is:

Where:

• Density — Measured in g/cm³ (or kg/m³)
• Mass — Measured in grams (g)
• Volume — Measured in cubic centimeters (cm³)

Explanation: Density describes how tightly matter is packed together. Higher density means more mass is concentrated in a given volume.

3. Importance of Density Calculation

Details: Density is crucial for identifying substances, determining buoyancy, and in engineering applications. It helps distinguish pure substances from mixtures.

4. Using the Calculator

Tips: Enter mass in grams and volume in cubic centimeters. Both values must be positive numbers. The calculator will compute density in g/cm³.

5. Frequently Asked Questions (FAQ)

Q1: What are common density units?
A: Common units include g/cm³ (for solids/liquids) and kg/m³ (for gases). 1 g/cm³ = 1000 kg/m³.

Q2: What's the density of water?
A: Pure water at 4°C has a density of 1 g/cm³. This serves as a reference point.

Q3: How does temperature affect density?
A: Most substances expand when heated (lower density) and contract when cooled (higher density), with water being a notable exception between 0-4°C.

Q4: What's the difference between density and specific gravity?
A: Specific gravity is density relative to water (dimensionless), while density has units of mass/volume.

Q5: How is density used in real-world applications?
A: Used in material identification, buoyancy calculations, quality control, and in designing ships and aircraft.
