Tungsten has a high melting point (over 3,400°C), which allows it to withstand the high temperatures generated when a light bulb filament heats up. It also has a high tensile strength, enabling it to maintain its structure under stress. Additionally, tungsten has a high resistance to corrosion, allowing the filament to have a longer lifespan in the bulb.

Why is the filament of a light bulb made from tungsten?

Tungsten is used because it has the highest melting point of all the metallic elements. It melts at 3410 degrees Celsius. When current passes through the filament it heats it up. When the filament reaches a certain temperature it starts to give off light, that's how you get a light bulb.


What physical properties of duct tape make it useful?

Duct tape is useful due to its strong adhesive properties, flexibility, durability, and water resistance. These properties allow it to bond to a variety of surfaces, conform to different shapes, withstand wear and tear, and provide a reliable solution for repairs and temporary fixes.
