Density practical

• Are solids generally denser than liquids?

  Yes, solids are generally denser than liquids.
• What are the steps to find the density of a solid object?

  1. Measure its mass using a balance.
  2. Calculate volume using a formula for regular shapes.
  3. For irregular shapes, submerge in a Eureka can to measure displaced water.
  4. Record the volume of water displaced.
  5. Use the formula: Density = Mass / Volume.
• What is the formula to find the volume of a cube?

  The volume of a cube is width × height × length.
• How can you find the volume of an irregular shaped solid?

  By submerging it in a Eureka can filled with water.
• What happens to the water when an irregular solid is submerged in a Eureka can?

  The water displaced by the object is transferred to the measuring cylinder.
• What should you do after recording the volume of water in the measuring cylinder?

  Plug the object's mass and volume into the density formula.
• What are the steps to find the density of a liquid?

  1. Place a measuring cylinder on a balance and zero it.
  2. Pour 10 ml of the liquid and record its mass.
  3. Add another 10 ml and record the total volume and mass.
  4. Repeat until the cylinder is full.
  5. Calculate density for each measurement.
  6. Take an average of the calculated densities.
• What is the relationship between milliliters and cubic centimeters?

  1 ml = 1 cm³.
• Why is it important to take an average of the calculated densities of a liquid?

  To get an accurate value for the density of the liquid.
• What is the general procedure for measuring density in different ways?

  • Measure mass using a balance.
  • Calculate volume using formulas or displacement.
  • Use the formula: Density = Mass / Volume.
  • Average multiple measurements for accuracy.
