How does smell travel through a house?

Smells travel through the air by a process called diffusion; air particles, and the odour particles within the air, move freely in all directions. They are constantly moving and eventually they spread out through the air around them.

Can a smell penetrate?

Chemicals with high volitile organic compounds can penetrate, but not all of them have much of a smell. Most solvents and pesticides fall in the smelly category. Formaldehyde and cyanide have distinct odors that can be called “penetrating”.
