👉 A chemical fluid, also known as a liquid or solution, is a homogeneous mixture composed of two or more substances where the components are uniformly distributed at the molecular level. In this state, the molecules are not fixed in space but move freely, allowing for the fluid properties such as viscosity, surface tension, and density to emerge. These fluids can be pure substances like water or salts dissolved in water, or mixtures such as air (composed of nitrogen, oxygen, argon, and trace gases) or oil and water emulsions. The interactions between molecules in a chemical fluid are governed by intermolecular forces, which dictate the fluid's behavior and properties. Understanding chemical fluids is crucial in various fields, including chemistry, physics, and engineering, as they underpin many natural processes and technological applications.
