1. What is the Sphere Density Equation?

The sphere density equation calculates the density of a spherical object by dividing its mass by its volume. Density is a fundamental property that indicates how much matter is packed into a given space.

2. How Does the Calculator Work?

The calculator uses the density equation:

Where:

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

Explanation: The equation shows the direct relationship between mass and density, and inverse relationship between volume and density.

3. Importance of Density Calculation

Details: Density calculations are essential in physics, engineering, and materials science for identifying substances, determining purity, and solving buoyancy problems.

4. Using the Calculator

Tips: Enter mass in grams and volume in cubic centimeters. Both values must be positive numbers. For accurate results, measure mass and volume precisely.

5. Frequently Asked Questions (FAQ)

Q1: What are typical density values for common materials?
A: Water is 1 g/cm³, aluminum ~2.7 g/cm³, iron ~7.87 g/cm³, gold ~19.3 g/cm³.

Q2: How does temperature affect density?
A: Most materials expand when heated (increasing volume), thus decreasing density. Water is densest at 4°C.

Q3: 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.

Q4: Can this calculator be used for non-spherical objects?
A: Yes, the density equation applies to any shape, but the title specifies spheres as a common application.

Q5: How precise should my measurements be?
A: Use at least 3 significant figures for both mass and volume for meaningful results.
