Key Concepts: Mass, Volume, & Density

Core Definitions

• the formula for density: Density = Mass / Volume
• the standard unit for mass: Kilogram (kg) or Gram (g)
• If mass increases while volume stays constant, what happens to density: It increases
• a method to find the volume of an irregular solid: Water displacement
• Is density a physical or chemical property: Physical
• Which is denser: Oil or Water: Water
• What happens if an object is less dense than the fluid it is in: It floats
• the unit for volume of a liquid: Milliliter (mL) or Liter (L)
• 1 mL is equivalent to how many cm^3: 1 cm^3
• Does density change with temperature: Yes, usually decreases as temperature increases
