1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It's a fundamental concept in physics and engineering that helps characterize materials and predict their behavior in different conditions.

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 the direct relationship between mass and density, and the inverse relationship between volume and density.

3. Importance of Density Calculation

Details: Density calculations are essential in material science, buoyancy calculations, fluid mechanics, and quality control processes. It helps identify substances and determine purity.

4. Using the Calculator

Tips: Enter mass in kilograms and volume in cubic meters. Both values must be positive numbers. The calculator will compute the density in kg/m³.

5. Frequently Asked Questions (FAQ)

Q1: What are common units for density?
A: The SI unit is kg/m³, but g/cm³ is also commonly used (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 is 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's the difference between density and specific gravity?
A: Specific gravity is the ratio of a substance's density to the density of water at 4°C (dimensionless).
