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.

2. How Does the Calculator Work?

The calculator uses the density formula:

Where:

• Mass — The amount of matter in an object (grams)
• Volume — The space the object occupies (cubic centimeters)

Explanation: The formula shows that density increases with greater mass or smaller volume, and decreases with smaller mass or greater volume.

3. Importance of Density Calculation

Details: Density measurements are crucial for identifying substances, determining purity, designing flotation devices, and understanding buoyancy principles.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What are typical density values for common liquids?
A: Water = 1 g/cm³, ethanol = 0.789 g/cm³, mercury = 13.6 g/cm³, olive oil = 0.92 g/cm³.

Q2: How does temperature affect density?
A: Most liquids expand when heated (lower density) and contract when cooled (higher density), with water being an important exception below 4°C.

Q3: What's the difference between mass and density?
A: Mass is the amount of matter, while density is how tightly that matter is packed into a given space.

Q4: Why does ice float on water?
A: Ice is less dense than liquid water (about 0.92 g/cm³ vs 1.00 g/cm³) due to its crystalline structure.

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