Q1. What is boling point tungsten ?
Ans. 
Boling point tungsten does not exist as tungsten has a very high melting point.
• Tungsten has a melting point of 3422°C, which is the highest of all metals.

• The boiling point of tungsten is not applicable as it does not exist in a liquid state under normal conditions.

• Tungsten is commonly used in high-temperature applications such as light bulb filaments and rocket nozzles.
