Verified step by step guidance1
Understand the definition of matter: Matter is anything that has mass and occupies space (has volume).
Analyze each option to see if it has mass and occupies space:
Air is a mixture of gases, which has mass and occupies space, so it qualifies as matter.
Heat is a form of energy transfer, not a substance with mass or volume, so it is not matter.
Sound is a mechanical wave that travels through a medium, but it itself does not have mass or volume, so it is not matter.
Light is electromagnetic radiation, which has energy but no mass or volume, so it is not matter.
