Understand the definition of matter: Matter is anything that has mass and occupies space (has volume).
Evaluate each option based on this definition: Heat is energy transfer and does not have mass or volume, so it is not matter.
Light is electromagnetic radiation and also does not have mass or volume, so it is not matter.
Sound is a mechanical wave that travels through a medium but itself does not have mass or volume, so it is not matter.
Air is a mixture of gases that has mass and occupies space, so it fits the definition of matter.
