What is the term for the measure of how much matter is in an object?

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

Answer: (B)

Mass is the amount of matter in an object. It tells us how much stuff something is made of and stays the same whether you’re on Earth or in space, because it’s about the material itself, not gravity. We measure mass with a balance or scale in units like grams or kilograms. Volume is how much space the object takes up. Weight is the pull of gravity on that mass, so weight can change with different gravity. Density is how much mass is packed into a given volume, mass per volume. Because mass directly measures the amount of matter, it is the best term for this question.
