Fluid mixtures are combinations of two or more fluids, which can include liquids, gases, or both. These mixtures can occur naturally, like in the case of air containing water vapor, or be created artificially, such as in oil and water emulsions. The properties of fluid mixtures depend on the types of fluids involved and their proportions. The behavior of fluid mixtures is influenced by factors like temperature, pressure, and the interactions between the different components. For example, in a suspension, solid particles are dispersed in a liquid, while in a solution, one fluid completely dissolves in another. Understanding these mixtures is essential in fields like chemistry and engineering.
