The measure of amount of matter in an object is called __ * 1 point a) Volume b) Energy c) Mass d) Size
The Correct Answer and Explanation is:
Correct Answer: c) Mass
Explanation:
Mass is the measure of the amount of matter in an object. It refers to the quantity of particles—such as atoms and molecules—that make up the substance. Mass remains constant regardless of the object’s location, even in space, unlike weight, which changes with gravity.
Mass is a fundamental property in physics and is measured in units such as grams (g), kilograms (kg), or milligrams (mg) in the metric system. Unlike volume, which measures the amount of space an object occupies, or energy, which refers to the ability to do work, mass specifically refers to how much “stuff” is in an object. It does not change unless the object itself gains or loses matter.
Understanding mass is crucial for many scientific disciplines. In chemistry, mass helps determine the proportions of substances involved in reactions. In physics, mass affects motion through Newton’s Second Law of Motion (Force = Mass × Acceleration). In astronomy, the mass of celestial bodies determines their gravitational pull and interactions with other bodies.
Mass also differs from size. Two objects may be the same size but have different masses if one is made of denser material. For example, a basketball and a bowling ball may have similar volume, but the bowling ball has more mass because it contains more matter packed into the same space.
In daily life, mass is often confused with weight, but weight is the force exerted by gravity on an object’s mass. On the Moon, where gravity is weaker, an object weighs less but its mass remains unchanged.
Therefore, the measure of the amount of matter in an object is most accurately described by the term mass.
