The word is "diffusion." It refers to the movement of gas particles from an area of higher concentration to an area of lower concentration.
In the gas phase, molecules will evenly fill the size of the container they are placed in. This is because gas molecules have high kinetic energy and are in constant motion, spreading out to fill the available space.
Seafloor spreading explained WHY and how Continental Drift occurs. How can lands be 'moving' without a catastrophic or even noticeable change--- seafloor spreading accounts for these small changes. It identifies where the actual changes take place (even if we cannot identify the exact spots where spreading occurs). We can better estimate how much the "spreading" equates to observable/measurable changes of continents, specifically how fast (slowly) continents are moving closer or further apart. Seafloor spreading explains other phenomena, too, like the expulsion of methane gas pockets at the ocean floor which are suspected to interfere with flotation of ships and possibly the downing of airplanes that pass over where methane is released when methane gas disrupts the air above the water. Seafloor spreading also gives clues as to how mountains and valleys form underwater and on land.
A gas that is not man-made or refined.
Gasoline is called "gas" as a shortened form of the word "gasoline," which is a liquid fuel derived from petroleum. The term "gas" for gasoline is a colloquial or informal usage, similar to how Americans refer to gasoline as "petrol" in the UK.

Diffusion is the scientific term for the movement of gas molecules from a region of higher concentration to a region of lower concentration until the concentration is uniform.

Dispersed
you could say 'quickly profused' if its spreading in a bad or harmful way then the word is 'insidious'
