👉 A semifluctuant is a term used in physics and engineering, specifically related to the motion of fluids. It refers to a phenomenon where a small amount of fluid (such as water or air) can change its state from being relatively dense (like liquid) to being more than slightly less dense (like gas), without changing its volume significantly. This is due to the viscosity of the fluid, which limits how much it can flow at one point in space.
