Liquid the distances between the molecules become smaller. When the liquid reaches its freezing point the molecules will usually lock into a very specific order, called crystallizing, and the bonds between them become more rigid, changing the liquid into its solid state (unless supercooling occurs). Only two elements are liquid at standard conditions for temperature and pressure: mercury and bromine. Four more elements have melting points slightly above room temperature: francium, caesium, gallium and rubidium. Metal alloys that are liquid at room temperature include NaK, a sodium-potassium metal alloy, galinstan, a fusible alloy liquid, and some amalgams (alloys involving mercury). Pure
Temperature chaining circuit. This means that the facility does not only reject the heat, but also the water which contains the heat to allow an external party to transport and use the warmed-up liquid. This results in a complete lack of cooling installations and the datacentre effectively acts like a large water heater. Water flows into the datacentre and comes out at high temperatures. The ILC racks in this setup effectively function as air handlers which maintain the entire room temperature and absorb all thermal energy leakage from the DLC and TLC environments. In smaller footprints, temperature chaining can be achieved by
