Density

• What is the first step in calculating the density of a regularly shaped object?

  Measure the dimensions and calculate the volume
• What is the second step in calculating the density of a regularly shaped object?

  Measure the mass using a calibrated balance
• How is density calculated from mass and volume?

  Density is calculated by dividing mass by volume
• What is the formula for the volume of a prism?

  Volume = area of face x height
• What equation is used to calculate the volume of a rectangular prism?

  Volume = Length x Width x Height
• What is the formula for the volume of a sphere?

  Volume = $\frac{4}{3} \pi r^3$
• What equation is used to calculate density?

  Density = Mass / Volume
• What unit is used for density?

  kg/m³
• What equipment is used to measure an object's mass?

  A digital balance, which must be zeroed
• What is the second step in calculating the density of an irregularly shaped object?

  Fill a displacement can with water
• How do you convert from g/cm³ to kg/m³?

  Multiply the value by 1000
• What is the first step in calculating the density of an irregularly shaped object?

  Measure the mass of the irregular shape
• What should you do after submerging the object in the displacement can?

  Record the volume of water displaced
• What is the last step in calculating the density of an irregularly shaped object?

  Calculate density from mass and volume
• What should be placed under the can spout to collect water?

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

  Fill until water drips from the spout
• What is the first step in calculating the density of a liquid?

  Measure the mass of the empty measuring cylinder
• What should you do after pouring liquid into the measuring cylinder?

  Record the volume of the liquid
• How do you find the mass of the liquid in the cylinder?

  Subtract the cylinder's mass from total mass
• How do the densities of solids and liquids generally compare?

  Solids are more dense than liquids
