1. What is Density?

Density is a physical property of matter defined as mass per unit volume. It is a fundamental concept in physics and engineering that helps characterize materials and substances.

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 calculates how much mass is contained in a given volume of a substance.

3. Importance of Density Calculation

Details: Density calculations are essential in material science, fluid mechanics, buoyancy studies, and various engineering applications. It helps identify substances and determine their purity.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are common units for density?
A: While kg/m³ is the SI unit, g/cm³ and g/mL are also commonly used, especially in chemistry.

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 has a density of approximately 1000 kg/m³ at 4°C.

Q4: Can density be used to identify materials?
A: Yes, different materials have characteristic densities that can help in identification.

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