Liquid metal Liquid metal Liquid metal consists of alloys with very low melting points which form a eutectic that is liquid at room temperature. The standard metal used to be mercury, but gallium-based alloys, which are lower both in their vapor pressure at room temperature and toxicity, are being used as a replacement in various applications. A few elemental metals are liquid at or near room temperature. The most well known is mercury(Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F). Others include caesium(Cs), which has a melting point of 28.5 °C (83.3 °F), rubidium (Rb)(39 °C [102 °F]), francium
Temperature dependence of liquid viscosity and applies over a large temperature and viscosity range: where "T" is absolute temperature in kelvins, formula_26 is the kinematic viscosity in centistokes, formula_27 is the zero order modified Bessel function of the second kind, and "A" and "B" are liquid specific values. This form should not be applied to ammonia or water viscosity over a large temperature range. For liquid metal viscosity as a function of temperature, Seeton proposed: Temperature dependence of liquid viscosity The temperature dependence of liquid viscosity is the phenomenon by which liquid viscosity tends to decrease (or, alternatively, its "fluidity" tends to increase) as its
