Argon, an inert noble gas, is commonly used to fill certain types of incandescent light bulbs for what practical purpose?

Explanation

Argon, an inert and chemically unreactive noble gas, is commonly used to fill certain types of incandescent light bulbs specifically to help prevent the extremely hot metal filament inside from reacting with oxygen and oxidizing, which would otherwise cause it to burn out much more quickly. Because argon does not react readily with the hot filament, it allows the bulb to operate for a significantly longer useful lifespan compared to a bulb filled with ordinary air. Argon’s inert properties also make it useful in various other applications where preventing unwanted chemical reactions with sensitive materials is important.
