What is the reason of Persistent Glowness of Platinum metal after removing it from the flame ?

Please elaborate - your question as posted doesn't make much sense.

I want to say " A platinum wire is heated in Bunsen burner and it is found to glow after removing the Platinum wire from the flame. Why?"

First of all - WHY does it glow?

The persistent glow of platinum metal after heating is due to its high melting point and thermal conductivity. Platinum has a melting point of 1768.3°C, which means it can withstand high temperatures without melting or losing its shape. When heated, the metal absorbs and stores thermal energy, causing its atoms to vibrate and emit light in the form of a glow.

Even after removing the platinum from the flame, it continues to radiate this stored thermal energy in the form of light, resulting in its persistent glow. This phenomenon is known as incandescence and is a property of metals with high melting points and thermal conductivity.

Additionally, platinum is a noble metal, meaning it is resistant to oxidation and does not easily react with other elements. This further contributes to its persistent glow as it does not form a dull oxide layer on its surface when exposed to air.

In conclusion, the persistent glow of platinum metal after heating is a result of its high melting point, thermal conductivity, and noble properties.
