which of the following is not an example of matter?
∘ smoke
∘ air
∘ heat
∘ water vapor

Explanation:

Matter is anything that has mass and takes up space (has volume). Smoke is made of tiny solid particles and gases, so it has mass and volume. Air is a mixture of gases, which have mass and occupy space. Water vapor is gaseous water, so it has mass and volume. Heat is a form of energy transfer, not a substance with mass and volume, so it's not matter.

Answer:

C. heat
