density required practical

• Density


  The mass per unit volume of a material
• Density is calculated using the equation: density = mass / volume
• The unit of density is kilograms per meter cubed
• Types of objects


  • Regular objects
  • Irregular objects
• Regular objects


  • Have dimensions that are easy to measure
• Determining density of regular objects

  1. Measure mass using a balance

  2. Measure dimensions using a ruler

  3. Calculate volume from dimensions

  4. Calculate density using density equation
• Irregular objects


  Cannot easily measure dimensions
• Determining density of irregular objects

  1. Measure mass using a balance

  2. Use displacement method to measure volume

  3. Calculate density using density equation
• The volume of water displaced is equal to the volume of the object
