A contractor needs to choose a low-density material for use in the construction of a building. When comparing two materials of the same size, the less dense material always gives a building structure which of the following characteristics?
A)lower weight
B)greater strength
C)lower flammability
D)greater electrical conductivity

Question

Quizplus · Accepted Answer

Lower density materials have less mass per unit volume, which results in a lower weight for the same size object. Strength, flammability, and electrical conductivity are properties that depend on the material's composition and structure, not directly on its density.
