Which properties of the metal tungsten make it useful in the thin glowing filaments of light bulbs?
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.
What are 3 intensive physical properties?
Density, melting point, and boiling point are three examples of intensive physical properties. These properties do not depend on the amount of substance present and are useful for identifying and characterizing materials.
Is silver a semiconductor, or does it have different electrical properties?
Silver is not a semiconductor; it is a metal with different electrical properties. Silver is a good conductor of electricity due to its high conductivity, making it useful in various electrical applications.
What are some properties of light given off by lasers?
Some properties of light emitted by lasers include coherence (waves are in phase), directionality (highly focused beam), monochromaticity (single wavelength), and high intensity. These properties make lasers useful in a wide range of applications such as cutting, welding, communication, and medical procedures.
What elements melts at 1455 c and boils at 1499 c?
The element that melts at 1455°C and boils at 1499°C is tungsten. Tungsten has a high melting and boiling point, making it useful for applications in high-temperature environments such as light bulb filaments and aerospace components.
What transition metal has a melting point of 961.93 Celsius?
The transition metal with a melting point of 961.93 degrees Celsius is Tungsten, which has the chemical symbol W. Tungsten is known for its high melting point, making it useful in applications that involve high temperatures such as light bulb filaments and aerospace components.
How is tungsten used in a tv?
Tungsten is primarily used in the production of the cathode in cathode ray tube (CRT) televisions, where it serves as the filament that emits electrons when heated. Additionally, tungsten's high density and durability make it useful in various components for shielding and structural support in modern TVs. While CRTs are largely obsolete, tungsten's properties can still be relevant in certain high-performance display technologies.
Uses of tungsten?
Tungsten's many alloys have numerous applications, most notably in incandescent light bulb filaments, X-ray tubes (as both the filament and target), and superalloys. Tungsten's hardness and high density give it military applications in penetrating projectiles. Tungsten compounds are most often used industrially as catalysts.
What are novel applications of tungsten alloys?
The hardness and heat resistance of tungsten can contribute to useful alloys. Tungsten's high melting point makes tungsten a good material for applications like submarine ballistics. Tungsten alloys are used in a wide range of applications, including the aerospace and automotive industries and radiation shielding.Superalloys containing tungsten, such as Hastelloy are used in turbine blades and resistants. Tungsten's heat resistance makes it useful in composite applications as can be a highly-conductive metal to withstand the high temperatures.
What are some uses for tungsten?
