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 Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( \rho \) — Density (kg/m³)
• \( m \) — Mass (kg)
• \( V \) — Volume (m³)

Explanation: The formula shows that density increases with greater mass or smaller volume.

3. Importance of Density Calculation

Details: Density is crucial for material identification, buoyancy calculations, and in many engineering and scientific applications.

4. Using the Calculator

Tips: Enter mass in kilograms and volume in cubic meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are common density units?
A: While kg/m³ is standard, g/cm³ is also common (1 g/cm³ = 1000 kg/m³).

Q2: How does temperature affect density?
A: For most substances, density decreases with increasing temperature due to thermal expansion.

Q3: What's the density of water?
A: Pure water at 4°C has a density of 1000 kg/m³ (1 g/cm³).

Q4: Can density be used to identify materials?
A: Yes, density is a characteristic property that can help identify pure substances.

Q5: What is relative density?
A: Relative density (specific gravity) is the ratio of a substance's density to that of water.
