Question

A strong metal used as filament in the bulb,its melting point is
3480 degree Celsius
3380 degree Celsius
3880 degree Celsius
4380 degree Celsius​

Answer 1

Answer:

tungsten is the filament in bulb andbits melting point is 3880 degree Celsius

Answer 2

The melting point of filament of a bulb is very high because the bulb begins to glow only when the filament is heated to a high temperature,and it becomes incandescent (bright) without melting.Hence, the material used in the filament of an electric bulb must have a high melting point.

It's melting point is near about 3400°C or 6200°F

So, from the above options it could be option (B) that is 3380° C or (A) 3480 because they are the nearest to the answer.

Hope it helps you...☺️
