Which of these has the highest volume

A. 1 kg of lead
B. 1 kg of iron
C. 1kg of gold
D. 1 kg of aluminum

1 answer

To determine which of the materials has the highest volume when comparing equal masses (1 kg), we need to consider the densities of each material:

  • Lead: Density ≈ 11,343 kg/m³
  • Iron: Density ≈ 7,874 kg/m³
  • Gold: Density ≈ 19,320 kg/m³
  • Aluminum: Density ≈ 2,700 kg/m³

Using the formula for volume (Volume = Mass / Density), we can calculate the volume of each material:

A. Lead:
Volume = 1 kg / 11,343 kg/m³ ≈ 0.0881 m³

B. Iron:
Volume = 1 kg / 7,874 kg/m³ ≈ 0.127 m³

C. Gold:
Volume = 1 kg / 19,320 kg/m³ ≈ 0.0518 m³

D. Aluminum:
Volume = 1 kg / 2,700 kg/m³ ≈ 0.370 m³

Now, comparing the volumes calculated:

  • Lead: ≈ 0.0881 m³
  • Iron: ≈ 0.127 m³
  • Gold: ≈ 0.0518 m³
  • Aluminum: ≈ 0.370 m³

Aluminum has the highest volume among the choices provided. Thus, the answer is:

D. 1 kg of aluminum
