New cards
  • define density

  • the mass of an object per unit volume

2
New cards
  • state the formula for density

  • ρ = m/v

    • density (kgm-3) = mass (kg) / volume (m3)

3
New cards
  • describe how to determine the density of an irregularly shaped object

  • measure the mass of the object using a digital balance

  • measure the volume of water in a measuring cylinder

  • submerge the object in the water

  • measure the new volume of the water

  • volume difference = volume of the object

  • ρ = m/v
