Question

True
False

Answer 1

True. The reason you can smell popcorn in a movie theater is indeed due to the diffusion of gases through the air. The popcorn emits volatile compounds that spread out as they move from an area of higher concentration (near the popcorn) to areas of lower concentration, allowing you to smell it even from a distance.
