Question

which statement best describes matter?
a) matter is anything that can be seen.
b) matter is anything that has mass and takes up space.
c) matter is anything that moves.
d) matter is anything that produces light.

Explanation:

Matter is defined as anything that has mass and takes up space (volume). Option A is incorrect because some matter (e.g., air) cannot be seen. Option C is wrong as not all moving things are matter (e.g., light "moves" but is not matter). Option D is incorrect because producing light is not a defining characteristic of matter.

Answer:

B. Matter is anything that has mass and takes up space.
