NaK containing 40% to 90% potassium by mass is liquid at room temperature.The eutectic mixture consists of 77% potassium and 23% sodium by mass (NaK-77), and it is a liquid from −12.6 to 785 °C (9.3 to 1,445.0 °F), and has a density of 0.866 g/cm 3 at 21 °C (70 °F) and 0.855 g/cm 3 at 100 °C (212 °F), making it less dense than water.

Molten FLiBe (2LiF·BeF 2). Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid, and molten salts are technically a class of ionic liquids.
The speed of sound in any chemical element in the fluid phase has one temperature ... 19 K potassium; use: 2000: 20 °C ... Values are "at room temperature" unless ...
Temperature response, e.g., Wood's metal and Field's metal for fire sprinklers; Non-toxic mercury replacements, such as galinstan; Experimental glassy metals, with extremely high strength and corrosion resistance; Eutectic alloys of sodium and potassium that are liquid at room temperature and used as coolant in experimental fast neutron nuclear ...
Potassium nitrate has an orthorhombic crystal structure at room temperature, [31] which transforms to a trigonal system at 128 °C (262 °F). On cooling from 200 °C (392 °F), another trigonal phase forms between 124 °C (255 °F) and 100 °C (212 °F).
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
Sodium-potassium alloy (NaK) phase diagram, ... Because NaK is a liquid at room temperature, the coolant does not solidify in the pipes. [83]
