Why does smell from stinky gym socks can spread across a room why this happens in terms of concentrations of particles?

The smell from stinky gym socks spreads across a room due to the diffusion of volatile compounds released by bacteria breaking down sweat and organic materials. These compounds, which are present in higher concentrations close to the socks, move to areas of lower concentration, gradually dispersing throughout the air in the room. This process continues until the concentration of odor particles becomes more uniform, allowing the smell to be detected from a distance.
