Study Notes
Density Definition
- Density is a physical property of matter.
- It is defined as mass per unit volume.
- The formula for density is: Density = Mass / Volume.
Units of Measurement
- The standard unit of density is kilograms per cubic meter (kg/m³).
- Other units include grams per cubic centimeter (g/cm³) and pounds per cubic foot (lb/ft³).
Key Concepts
- Density describes how tightly packed matter is.
- Higher density means more mass is concentrated in a smaller volume.
- Lower density means less mass is concentrated in a larger volume.
Applications
- Density plays a crucial role in various fields.
- In determining the buoyancy of objects, (objects less dense than the surrounding liquid will float).
- In identifying substances as different materials have different densities.
- In understanding the behavior of fluids and gases.
Factors Affecting Density
- Mass: A greater mass leads to a higher density, given the volume remains constant.
- Volume: A smaller volume leads to a higher density, provided the mass remains constant.
