AI overview

Diffusion is the process where particles randomly move around and gradually spread out from areas where they're concentrated to areas where they're sparse, until they're distributed evenly throughout. This matters because it's a fundamental way that substances mix and spread in liquids and other materials, happening naturally without any external force pushing them along.

拡散（かくさん、英: diffusion）とは、粒子、熱、運動量、等が、散らばり、広がる、物理的な現象。この現象は着色した水を無色の水に滴下したとき、煙が空気中に広がるときなど、日常よく見られる。これらは、化学反応や外力ではなく、流体の乱雑な運動の結果として起こるものである。
