Compare the density, weight, mass, and volume of a pound of gold to a pound of iron on the surface of Earth.

Mass of gold = mass of iron

weight of gold = weight of iron

volume of gold is less than the volume of iron

Explanation:

mass of gold = 1 pound

mass of iron = 1 pound

Mass of both the metals is same.

Weight is equal to the product of mass and the acceleration due to gravity. As acceleration due to gravity is same for both the metals so the weight of both the metals is same.

As the density of iron is less than the density of gold and we know that the volume is defined as the ratio of mass to the density.

mass is same for both the metals, so the volume of iron is more than the density of gold.

Mass of gold = mass of iron

weight of gold = weight of iron

volume of gold is less than the volume of iron
