you were given four blocks of different substances such as lead, iron, alumnum and a wood of same of same volume, compare their masses, what conclusion would you draw from it



Answer :

Lead will have the highest mass, followed by iron, aluminum, and wood. This demonstrates that denser substances have greater mass given the same volume.

This question revolves around the concept of density. Density is defined as mass per unit volume, and different substances have different densities.

[tex]density=\frac{mass}{volume}[/tex]

For the same volume, the material with higher density will have higher mass.

Here’s a comparison of the masses of the four blocks (lead, iron, aluminum, and wood), considering they all have the same volume:

  • Lead: Lead has a high density (approximately 11.34 g/cm³).
  • Iron: Iron has a lower density compared to lead (approximately 7.87 g/cm³) but is still relatively high.
  • Aluminum: Aluminum has a significantly lower density than both lead and iron (approximately 2.70 g/cm³).
  • Wood: Wood has the lowest density among the four (ranging from about 0.2 to 0.9 g/cm³ depending on the type of wood).

From the above data, we can conclude that for the same volume, the mass of the substances will vary. Lead will have the greatest mass, followed by iron, aluminum, and finally wood which will have the least mass.
