👉 Superfluidity is a state of matter that has both a significant amount of energy and a high degree of thermal conductivity, which allows it to flow very quickly. In other words, superfluids are materials with a high temperature and low pressure that can flow at extremely high speeds. They are found in the liquid helium (He) and water states, as well as in certain types of superconductors. These materials have been used in various applications, including in spacecraft propulsion systems, where they serve
