Question

Metals are used in many products because of the characteristic properties that most metals share. Which properties of the metal tungsten make it useful in the thin, glowing filaments of light bulbs? A. Tungsten is electrically conductive, ductile, and opaque. B.Tungsten is ductile, is malleable, and has a high luster. C.Tungsten is ductile, has a high melting point, and is electrically conductive. D.Tungsten has a high luster, has a high melting point, and is silver in color.

Answer 1

Answer:

Option (c)

Explanation:

The characteristic properties of a metal tungsten are as follows :

1. It can be cut into hard steel. It means it is ductile.
2. It is the only metal which has highest melting point i.e. 3410 °C.
3. It has high temperature mechanical propoerty.
4. It has luster.

Out of the given options, option (c) gives the best properties of the metal tungsten make it useful in the thin, glowing filaments of light bulbs i.e. ".Tungsten is ductile, has a high melting point, and is electrically conductive"
