👉 A compound fluid is a mixture of two or more different substances that are physically combined without undergoing any chemical reaction to form a new substance. These fluids can be liquids, gases, or even solids suspended in another medium, and they often exhibit properties that are intermediate between those of their individual components. For example, emulsions like mayonnaise (oil and vinegar) or foams (air and liquid) are examples of compound fluids, where two immiscible liquids are combined to create a stable mixture. The behavior of compound fluids is governed by principles of thermodynamics and can be influenced by factors such as temperature, pressure, and the interactions between the different components.
