Can't think of the right word...(scientific term)

Factual Questions
1

Hey guys, I have a question about what the best scientific term is that describes the general physical/chemical phenomenon in which a bunch of objects/entities/particles starts off clumped together closely and then with the passage of time spreads out so that the particle separation distance increases with time. It’s on the tip of my tongue but I can’t seem to remember it…

Thanks.
Jay
