👉 A substitute fluid is a liquid or gas used as an alternative to water in various industrial, scientific, and medical processes when water is not suitable or available. This fluid can be engineered to have specific properties such as lower freezing points, higher thermal stability, or enhanced solubility, making it ideal for processes requiring water's unique characteristics but under different conditions. Substitute fluids are crucial in applications like cryopreservation, where they prevent ice crystal formation, or in chemical reactions where water might be toxic or incompatible. Their use extends to medical settings for intravenous fluids, where they can mimic human blood properties, and in environmental applications, such as wastewater treatment, where they help in breaking down pollutants without causing harm to the ecosystem.
