Question

The density of a large piece of iron and a small piece of iron will be the same because ______.

A. Density is the same for all objects
B. Density is independent of object size
C. Density is a mathematical equation
D. The smaller piece fits inside the larger piece

Answer 1

The density of iron remains constant regardless of the size of the iron piece because density is an intensive property, defined as mass per unit volume and does not depend on the amount of material.

Step-by-step explanation:

The density of a large piece of iron and a small piece of iron will be the same because density is independent of object size. Density is a physical property that does not change with the quantity of the material. It's defined as the mass of the substance divided by its volume. Regardless of whether we have a tiny chunk of iron or a colossal slab, the density remains constant for a given substance. The equation for density is p=m/V, where p represents density, m is mass, and V is volume. Therefore, two pieces of iron made of the same material will have the same density, be it in grams per cubic centimeter (g/cm³) or another unit of mass per unit volume.
