What is matter?

What is matter?

• A. Anything that is colored
• B. Anything that has mass and takes up space
• C. Anything that is visible
• D. Anything that can be compressed

Answer: (B)

Matter is the stuff that makes up the physical world and is defined by having mass and occupying space. Mass is the amount of material present, while volume is how much space that material takes up. Everything from a rock to a drop of water to the air around you fits this definition because they have mass and occupy space. Things like color or visibility describe how we perceive matter, not whether something is matter. For example, light and heat aren’t matter because they don’t have mass in the usual sense and don’t occupy space like a lump of material. Some matter can be invisible or compressible, but those properties don’t determine whether something is matter.
