Explanation:
1. Introduction:
Inactive nitrogen and argon gases are commonly used in electric bulbs for various reasons. This question asks us to identify the purpose of using these gases in electric bulbs.
2. Increase the intensity of light emitted:
Inactive nitrogen and argon gases do not contribute to increasing the intensity of light emitted. Therefore, option a) is incorrect.
3. Make the emitted light coloured:
Inactive nitrogen and argon gases do not have any effect on the color of the emitted light. Therefore, option c) is incorrect.
4. Make the production of bulb economical:
Although the use of inactive nitrogen and argon gases may have some impact on the production cost of bulbs, it is not the primary reason for their use. Therefore, option d) is incorrect.
5. Increase the life of the filament:
The correct answer is option b) - Increase the life of the filament. Inactive nitrogen and argon gases are used in electric bulbs to increase the lifespan of the filament.
5. Explanation:
- The filament in an electric bulb is responsible for producing light when an electric current passes through it.
- However, the high temperatures generated by the filament can cause it to degrade over time, resulting in reduced lifespan.
- Inactive nitrogen and argon gases are used in electric bulbs because they are chemically inert and do not react with the filament or other components of the bulb.
- These gases help in reducing the evaporation and degradation of the filament, thereby increasing its lifespan.
- By using inactive gases, the filament can operate at higher temperatures without degrading quickly, leading to a longer bulb life.
6. Conclusion:
In conclusion, inactive nitrogen and argon gases are used in electric bulbs primarily to increase the life of the filament. They do not affect the intensity or color of the emitted light.
