👉 An active fluid, often referred to as a liquid metal or liquid alloy in certain contexts, is a state of matter where the constituent particles—typically atoms or molecules—are in constant, rapid motion, yet they are not confined to fixed positions as in a solid. This fluidity allows the particles to flow and change shape while maintaining a continuous medium, enabling properties like viscosity and surface tension. Active fluids are crucial in various applications, such as cooling systems in electronics, where their ability to efficiently transfer heat away from components is vital. They can also be found in specialized industrial processes, like casting and welding, where their fluid nature facilitates shaping and solidification. The term "active" underscores their dynamic behavior, distinct from inert fluids that do not flow or change shape under normal conditions.
