Helium is very difficult to liquify because it only exists in its liquid form at an extremely low temperature. This temperature is <span>low temperature of −269 °C (about 4 K or −452.2 °F). It is only possible to maintain liquid helium in a highly artificial environment where this low temperature can be created. </span>
