Understanding Density
Before diving into the answer key, it's essential to grasp the concept of density itself. Density is defined as the mass of an object divided by its volume, typically expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). The formula for density is:
Density Formula
Density (D) = Mass (M) / Volume (V)
Factors Affecting Density
Several factors can influence the density of a substance:
- Temperature: As temperature increases, most materials expand, leading to a decrease in density.
- Pressure: For gases, increasing pressure can compress the material, increasing its density.
- Composition: Different materials have intrinsic densities based on their atomic structure and mass.
