The melting point is a physical property that determines the temperature at which the metal changes its state from solid to liquid.
The melting point of potassium is 63.5°C or 146.3°F. Potassium is a highly reactive metal and is not found in its elemental form in nature. It is commonly obtained through the electrolysis of potassium chloride, which is obtained from mineral deposits.
Potassium has many important applications, including use in agriculture as a fertilizer, in medicine as a cardiac stimulant, and in the industry as an ingredient in the manufacture of soaps, dyes, and other products.
