Anything that has mass and occupies space is called what?

• A. Energy
• B. Matter
• C. Mass
• D. Volume

Answer: (B)

Matter is anything that has mass and takes up space. That description matches objects and substances you encounter every day, like wood, water, air, and rocks. Mass measures how much matter something contains, while volume measures how much space it occupies. Energy, by contrast, is the ability to do work and can exist without having mass in many forms (for example, light carries energy but has no rest mass). Volume describes space, not what something is, and mass describes how much matter, not the substance itself. So the statement is defining matter—the stuff that makes up the universe.
