1. What is Density?

Density is a physical property of matter defined as mass per unit volume. For a sphere, it helps determine the compactness of the material it's made of.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• \( D \) — Density (g/cm³)
• \( M \) — Mass (g)
• \( V \) — Volume (cm³)

Explanation: The formula calculates how much mass is contained in a given volume of the sphere.

3. Importance of Density Calculation

Details: Density is crucial for identifying materials, determining buoyancy, and understanding material properties in physics and engineering applications.

4. Using the Calculator

Tips: Enter mass in grams and volume in cubic centimeters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical density values for common materials?
A: Water is 1 g/cm³, aluminum about 2.7 g/cm³, and lead about 11.34 g/cm³.

Q2: How does temperature affect density?
A: Density generally decreases with increasing temperature as materials expand.

Q3: What's the difference between density and specific gravity?
A: Specific gravity is density relative to water (dimensionless), while density has units.

Q4: Can this calculator be used for irregular shapes?
A: Yes, as long as you know the exact volume of the object.

Q5: Why is density important for spheres?
A: It helps determine buoyancy, material composition, and is essential in fluid mechanics calculations.
