👉 The w-fluid, also known as water-fluid or water-wet fluid, is a term used in physics to describe a type of fluid that adheres strongly to surfaces, typically due to cohesive forces between water molecules and adhesive forces between the fluid and the surface it contacts. This strong adhesion results in high surface tension, which allows water to form droplets, climb up narrow tubes (capillary action), and exhibit other characteristic behaviors. In contrast to oil, which is an oily fluid that repels water, water's w-fluid properties make it essential for various natural processes, including the transport of nutrients in plants and the movement of organisms in aquatic environments.
