👉 A fluid in this context refers to a substance that can flow easily and smoothly, typically under specific conditions of temperature and pressure. Fluids have no fixed shape but take the form of their container, meaning they can spread out to fill any space. They exhibit properties like viscosity, which is a measure of their resistance to flow, and surface tension, which allows them to form droplets or maintain interfaces with other substances. Examples of fluids include water, oil, and air, each with unique characteristics that define their behavior in various environments.
