send messages
to your brain, which identifies the smell.
How do smells dissipate?
Smells ‘disappear’
when the aroma molecules disperse in the air to a concentration below your detection threshold

How fast do smells travel?

there really is no “speed of smell”
and it depends a lot on the specific situation. The speeds of light and sound can vary depending upon the exact medium through which they are traveling, but these speeds are dependent upon fewer variables and thus much easier to determine.

Why do smells linger in my house?

Why do smells move slowly?
However, a smell does not travel this fast. This is because
its particles collide with each other and with particles of air very frequently
. They change direction randomly when they collide, so it takes much longer to travel from one place to another.
