Answer Details
The process that allows the odor of a leaking gas to be perceived at a distance from the source is diffusion. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration, resulting in the mixing of substances. In this case, the gas particles are moving from the source of the leak to the surrounding air, where they become more spread out and less concentrated. As a result, the odor can be detected even at some distance from the source due to the diffusion of the gas particles in the air.
