Part 2: Calculating the density of irregular shaped objects

• What is the first step in the practical procedure?

  Measure the mass of the irregular shape
• What should be done after measuring the mass of the object?

  Fill a displacement can with water
• What is the third step in the practical procedure?

  Record the volume of water displaced
• How do you calculate density in this practical?

  From the mass and volume
• What should you place under the can spout to collect the water?

  A measuring beaker
• How should you fill the displacement can for accuracy?

  Fill until water drips from the spout
• What should you do after the water starts dripping from the spout?

  Wait until the dripping just stops
• How do the densities of solids and liquids generally compare?

  Solids are more dense than liquids
• Why are solids generally more dense than liquids?

  Particles are more tightly packed together
• What does more mass per unit volume indicate about a substance?

  It indicates higher density
