The main difference between Mass and Density: Mass is the amount of matter in an object measured in kilograms, while density is the mass per unit volume of a substance. Mass remains constant everywhere
Mass vs Density — Comparison Table
| Basis | Mass | Density |
|---|---|---|
| Definition | Amount of matter in an object | Mass per unit volume of a substance |
| SI Unit | Kilogram (kg) | Kilogram per cubic meter (kg/m3) |
| Nature | Scalar quantity | Scalar quantity |
| Variation with Gravity | Remains constant everywhere in the universe | Remains constant for a pure substance at same temperature and pressure |
| Measurement | Measured using a balance | Calculated using formula: Density = Mass/Volume |
| Example | A 10 kg block has the same mass on Earth and Moon | Iron has density 7800 kg/m3 while water has density 1000 kg/m3 |
Key Points
- Mass is an intrinsic property while density is a derived property that depends on mass and volume
- Two objects can have the same mass but different densities if their volumes are different
- Density helps in identifying substances and understanding their floating or sinking behavior
- Mass is measured with a balance while density requires both mass and volume measurements
