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.

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 the inverse relationship between volume and density.

3. Importance of Density Calculation

Details: Density is crucial for material identification, buoyancy calculations, quality control in manufacturing, and many scientific applications. It helps distinguish between materials with similar appearances but different compositions.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are common density units?
A: Common units include g/cm³ (for solids and liquids) and kg/m³ (for gases). 1 g/cm³ equals 1000 kg/m³.

Q2: What is the density of water?
A: Pure water at 4°C has a density of exactly 1 g/cm³, which serves as a reference point for many calculations.

Q3: How does temperature affect density?
A: Most materials expand when heated (increasing volume), thus decreasing density. Water is unique as it reaches maximum density at 4°C.

Q4: What is specific gravity?
A: Specific gravity is the ratio of a material's density to the density of water (at 4°C), making it a dimensionless number.

Q5: How can I measure volume for irregular objects?
A: Use water displacement method - measure water volume before and after submerging the object, the difference is the object's volume.
