Look at this table.
|Row 1||It has 1 filament made of tungsten.||It is filled with argon gas.||Its connection points are at the base.|
|Row 2||It has 2 filaments of tungsten.||It is filled with argon gas and a small amount of mercury.||It has 2 connection points, one at each tip.||Its inner surface is covered with a phosphoric material.|
Which row shows the features of a fluorescent lamp?
Fill in the blanks: Tungsten is used as a filament in electric lamps because it has a . This prevents it from due to the heat of the lamp.
- Ahigh melting point, melting
- Blow melting point, melting
- Chigh boiling point, boiling
- Dlow boiling point, boiling
Look at this fluorescent lamp.
What is the function of the glass tube?
- AIt stops the filament melting.
- BIt connects the fluorescent lamp to the electricity source.
- CIt holds the argon gas and mercury vapor.
