Which term is described as 'Another word for mass. The amount of mass; pounds or kilograms'?

• A. Density
• B. Weight
• C. Volume
• D. Mass

Answer: (B)

The idea being tested is the difference between basic physical quantities and how we talk about them. The phrase describes a term that is literally the amount of matter in an object, typically measured in kilograms (though pounds are common in everyday usage). That is mass. Weight is related but different: it’s the gravitational force on a mass and is usually expressed as pounds-force, changing with gravity. Volume measures how much space something takes up, and density is mass per unit volume. So the term described by that definition is mass.
