P1.2 Density

• What are the units of density?


  $kg/m^3$ or $g/cm^3$
• Describe what density means, in words.


  Density is a measure of how much mass a substance has, per unit of its volume.
• What is the formula that links density, mass, and volume?


  Density (p) = mass (m) / volume (v)
• How might you experimentally calculate the density of an irregularly shapes object?


  1. Measure the object's mass using a balance.
  2. Use a Eureka can to measure the object's volume.
  3. Use the mass and volume to calculate the density.
• What is a fluid?


  A fluid is a substance in which the particles are free to move. So a fluid is any liquid or gas.
• How might you experimentally calculate the density of an irregularly shaped object?


  1. Measure the object's mass using a balance.
  2. Use Eureka can to measure the object's volume.
  3. Use the mass and volume to calculate density.
