Question

what is the burning temperature of potassium​

Answer 1

Answer:

Burning rate of potassium has been found to be in the range of 30–60 kg/m2s

Explanation:

What is Potassium?

• Potassium is the first element of the fourth period (row) in the periodic table.
• The atomic mass of potassium is 39.098 atomic mass units. It is denoted by the symbol ‘K’.
• The term potassium arises from a material called Potash.
• The element has been in use for hundreds of years.
• It is an alkali metal along with lithium, rubidium, sodium, caesium, and francium
• It is a very active metal and never occurs free in nature and it always forms a compound with other elements.

Isotopes Of Potassium

• Potassium usually has three isotopes, it goes by the name of potassium-39, 40 and 41. The potassium-40 is highly radioactive and can be found in rocks, plants, and animals. It is used to measure the age of objects. This isotope breaks down into an isotope of argon.

Uses Of Potassium

• It can be used as a medium of heat exchange and are used in nuclear power plants because of this reason
• People use potassium salts as a constituent of fertilizer.
• It is one of the essential nutrients of the human body
• Potassium chloride is also used in injections.
• Potash can be used to make glass and soap etc
• Physical and Chemical Properties Of Potassium
• It is soft and shiny metal which has a melting point 63 degrees and the boiling point as 770 degrees.
• Potassium metal can float on water
• It reacts with water violently and gives hydrogen which can actually catch fire and may explode
• It can readily react with chlorine, fluorine, sulphur, nitrogen and phosphorous.
• It has a green vapour and lavender coloured flame
• It is ranked as the 7th most abundant element present in the earth’s crust.
• The element is always traced in combination with other elements.
• Once isolated, potassium turns into a malleable metal with a silver colour profile.
• Potassium reacts with water violently and gives off hydrogen gas

Answer 2

Answer:

Burning rate of potassium has been found to be in the range of 30–60 kg/m2s for various conditions and is typically lower than that of sodium and lithium under similar conditions. Auto-ignition temperatures lie in the range of 500–650 K, the higher temperatures occurring in smaller pools and low oxygen concentrations.
