👉 An excited fluid is a state of matter that exists when a substance, typically a solid or liquid, is subjected to intense energy input, such as high temperatures or strong electromagnetic fields, causing its atoms or molecules to become highly excited and move more rapidly than in their ground state. This heightened energy leads to the breaking of chemical bonds and the formation of new ones, resulting in a fluid-like behavior where particles exhibit collective motion and can flow or diffuse rapidly. Excited fluids are of great interest in fields like plasma physics, materials science, and astrophysics, as they can mimic or model complex phenomena observed in stars, lightning, and other high-energy environments.
