👉 Fluids are substances that flow smoothly and freely without resistance. They can exist in various states, including gases, liquids, and solids. Fluids can be divided into three main types: solid, liquid, and gas. Solid fluids have a fixed shape and size, while liquid fluids are more fluid than solid ones and move with the flow of water or air. Gas fluids, such as helium, nitrogen, and argon, do not change their shape and are stable at low temperatures.
