The mass of a given volume of lead, its density, is a fundamental physical property. This characteristic is typically expressed as mass per unit volume, commonly using grams per cubic centimeter (g/cm) or kilograms per cubic meter (kg/m). For instance, a cube of lead measuring one centimeter on each side has a specific mass.
Understanding this property is essential in various applications, from balancing weights in machinery to radiation shielding and the manufacture of batteries. Historically, lead’s density played a role in its selection for construction, plumbing, and even ammunition. Its high density relative to other common materials made it suitable for these purposes, influencing architectural and engineering practices over centuries.
