The correct Answer is:
To solve the question, we need to determine what gas is used to fill a bulb in order to prevent the hot metal filament from burning when the electric current is switched on. ### Step-by-Step Solution: 1. **Understanding the Problem**: - The question states that we need to prevent the hot metal filament in a bulb from burning. The filament typically used in bulbs is made of tungsten, which can burn if exposed to oxygen at high temperatures. 2. **Identifying the Options**: - The options given are CH4 (methane), CO2 (carbon dioxide), Cl2 (chlorine), and an inert gas. 3. **Analyzing Each Option**: - **CH4 (Methane)**: This is a flammable gas. If the filament gets hot, methane could ignite, leading to a fire hazard. - **CO2 (Carbon Dioxide)**: This gas is non-flammable and can be used to extinguish flames. However, it does not prevent the filament from burning in the first place. - **Cl2 (Chlorine)**: This is a reactive gas and can be hazardous. It can react with metals and is not suitable for this application. - **Inert Gas**: Inert gases (like argon, neon, etc.) do not react with other substances. They can fill the bulb and prevent any combustion from occurring. 4. **Conclusion**: - The best option to fill the bulb to prevent the tungsten filament from burning is an inert gas. This is because inert gases do not react with the filament or support combustion, thus ensuring the filament remains intact when heated. ### Final Answer: The bulb is filled with an **inert gas**.
