Question

property of tungsten​

Answer 1

Answer:

Tungsten is used in electric bulb because it have a high melting point so that it does not melt even when it is high temperatures due to the passage of electric current.

Answer 2

Answer:

Among metals it has the highest melting point, at 3,410 °C (6,170 °F), the highest tensile strength at temperatures of more than 1,650 °C (3,002 °F), and the lowest coefficient of linear thermal expansion (4.43 × 10−6 per °C at 20 °C [68 °F]). Tungsten is ordinarily brittle at room temperature.

Explanation:

Melting point: 3,410 °C (6,152 °F)

Density: 19.3 grams/cm3 at 20 °C (68 °F)

Boiling point: 5,660 °C (10,220 °F)
