Do objects of the same material have the same density?

The statement that objects of the same material have the same density is based on the principle that density is an intrinsic property of a substance. Density is defined as mass per unit volume (density = mass/volume) and is typically consistent for a given material at a specific temperature and pressure.

When the material is the same, its molecular structure and composition are identical, which means its density remains constant regardless of the object's size or total mass. For instance, whether you have a small cube of gold or a large bar of gold, both will maintain the same density because they are composed of the same atoms arranged in the same way.

Density may change with variations in temperature and pressure, but provided these conditions are kept constant, the density remains the same for a specific material regardless of its size. Thus, it is valid to say that objects made from the same material exhibit the same density.
