What exactly are scents and why do we stop smelling them after a while?

Are they particles in the air that start all bunched up and then slowly spread out so thin to the point where it’s undetectable by the average human nose?

Anytime you smell something, it’s basically several little particles of varying compounds that enter your nose and come into contact with your olfactory mucosa (mucus) and is then detected by olfactory neurons. I believe each neuron is limited in what scents it’s able to detect so imagine one is good at detecting sulfur, another acetic acid.
So when you smell a fart, someone’s butt particle got right up in there for you to smell it.
