IPA: /ˌmaɪkroʊˈfɪzɪkəl/
KK: /maɪkroʊˈfɪzɪkəl/
Relating to the branch of physics that deals with very small particles, such as atoms and molecules.
The study of microphysical processes is essential for understanding the behavior of materials at the atomic level.
Microphysical → It is formed from "micro-" (from Greek "mikros", meaning small) and "physical" (from Greek "physikos", meaning pertaining to nature or natural). The word "microphysical" refers to the physical properties or phenomena that occur at a very small scale, often at the level of atoms and molecules.
Think of 'small' ('micro-') things that relate to 'nature' ('physical') — that's why microphysical describes the natural properties of very tiny elements.
