Question

In a presentation about measuring mass, one of your classmates states, "Two objects of the same size will always have the same mass.” Is this statement correct? Why or why not?

Answer 1

Answer: The statement is not correct.

Reason:

If two objects have the same mass, their respective densities determine their volumes.

By definition,

density = mass/volume.

or volume = mass/density.

Therefore if two objects have the same mass, the mode dense object (with higher density) will occupy less volume than the other object.
