👉 A weak fluid, also known as a low-viscosity fluid, is a substance that flows easily and with minimal resistance when subjected to a force. This property results from its low internal friction, often due to the small size and weak intermolecular forces between its constituent particles. Examples include water at room temperature, oil, and certain gases like helium. In practical terms, weak fluids can be easily poured, sprayed, or mixed with other substances, making them useful in various applications like lubrication, cooling systems, and industrial processes.
