Question

for anything to be considered matter, it must ______
○ have mass and take up space.
○ have mass and compounds
○ take up space and have energy
○ have compounds and energy

Explanation:

To determine what qualifies as matter, we recall the scientific definition: matter is anything that has mass and occupies space (volume). Let's analyze each option:

• "have mass and take up space": This matches the definition of matter. Mass is a measure of the amount of matter, and taking up space means having volume.
• "have mass and compounds": Compounds are a type of matter, but not all matter is a compound (e.g., elements like hydrogen are matter but not compounds), so this is incorrect.
• "take up space and have energy": Energy is not matter (matter has mass and volume; energy does not have mass or occupy space in the same way), so this is incorrect.
• "have compounds and energy": Similar to the above, energy is not matter, and not all matter is a compound, so this is incorrect.

Answer:

A. have mass and take up space.
