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 chemistry that helps identify substances and predict their behavior in different environments.

2. Density Formula

The density formula is expressed as:

Where:

• \( D \) — Density (g/mL or g/cm³)
• \( m \) — Mass (g)
• \( V \) — Volume (mL or cm³)

Explanation: This formula shows that density increases with greater mass and decreases with greater volume for a given substance.

3. How to Use This Calculator

Instructions: Enter any two known values (density, mass, or volume) and the calculator will compute the missing value. Leave the field you want to calculate empty.

4. Applications of Density

Details: Density calculations are essential in material science, engineering, geology, and many industrial processes. It helps identify substances, determine purity, and design flotation devices.

5. Frequently Asked Questions (FAQ)

Q1: What are common units for density?
A: The most common units are g/mL or g/cm³ for solids and liquids, and g/L for gases.

Q2: Why does ice float on water?
A: Ice has a lower density than liquid water due to its crystalline structure, making it float.

Q3: How does temperature affect density?
A: For most substances, density decreases as temperature increases due to thermal expansion.

Q4: What is the density of water?
A: Pure water has a density of approximately 1 g/mL at 4°C.

Q5: How is density used in industry?
A: Density measurements are used in quality control, material identification, and separation processes.
