Tungsten is the mineral used for tools, machinery, light bulb filaments, and steel girders. Its high melting point and strength make it ideal for these applications, particularly in producing durable and heat-resistant components. Additionally, tungsten is often alloyed with other metals to enhance their properties, making it valuable in various industrial uses.

What mineral uses tools machinery light-bulb filaments steel girders?
Tungsten is the mineral that is used in various applications such as tools, machinery, light-bulb filaments, and steel girders. Its high melting point and density make it ideal for manufacturing durable tools and components that can withstand extreme conditions. Additionally, tungsten is often used to reinforce steel, enhancing its strength and performance in construction and industrial applications.
Is the brightness of a light bulb determined by its filaments?
Though there is a bit more to the story than this, yes, it is generally true that the brightness of a light bulb, sometimes called a lamp, is a function of its filaments. For a given voltage of operation, a less resistive filament will draw more current, run hotter and will glow more brightly (be more incandescent). A heavier, more resistive filament will draw less current, get less hot, and not produce as much light (be less incandescent). The former will run "hotter" as well as brighter, and the filament won't last as long, though it will be more efficient. The latter will not be quite as bright or as efficient, but the filament will have a longer operating life, and will probably be more shock resistant. Lamp filaments are usually made of tungsten, and these filaments are coiled to reduce evaporation of the metal when that metal is white hot. There is a "balance" engineered into the lamp to make it run "hotter" and more brightly to be more efficient, yet limit current somewhat, limit filament evaporation and extend the life of the lamp. Eventually, enough of the filament evaporates away in normal operation to create a "hot spot" that quickly degrades, and the filament fails. A link can be found below to learn more.
What English engineer invented a special furnace?
The English engineer who invented a special furnace is Thomas Edison. He developed the first practical electric light bulb and also created the Edison Electric Light Company. His work on electric lighting systems included the design of a special furnace for manufacturing carbon filaments, which were crucial for the longevity and efficiency of his light bulbs. This innovation played a significant role in the widespread adoption of electric lighting.
What is the chemical or liquid inside a compass?
compasses have Mineral Oil filled Needle Housings, with steel needles that pivot on a sapphire bearing The light mineral oil is there to damp the needle (stop the needle swinging too loosely) and it has to withstand freezing (because compasses are used in cold places).
What is the principle of electric tube light?
The way an electric tube, or fluorescent, light works is really very interesting. Most "regular" light bulbs are incandescent. Their source of light is the glow of electricity passing through a very thin wire known as a filament that is suspended in a vacuum. It glows with a "warm" color in the yellow/orange range. With a fluorescent tube there are two filaments, but they do not directly provide the light source, and a mercury vapor instead of a vacuum.On each end of a long glass tube are coils using electricity regulated by a ballast. The tube is filled with mercury vapor and phosphor. The electricity passing through the filaments excites the mercury vapor causing it to glow with ultraviolet (black) light. Ultraviolet light is not visible, but it does cause cause certain chemicals and colors to glow or fluoresce. If you take laundry detergent with phosphorous in it, for example, and place it under an ultraviolet (black) light, the phosphorus glows cold white. So by adding Phosphorus to the tube of Mercury vapor it will also glow when the vapor is excited electrically.The result is a lot of light for a much lower amount of electricity, and excess heat. The color temperature is very close to that of daylight but a little cooler, in the blue/green range. That makes growing plants under fluorescent light more effective also. The negatives are that most "tube lights" can not be dimmed with a wall dimmer-switch, and the ballasts, that controls electrical flow, do have a tendency to burn out or fail after a time.

What mineral is used in tools and machinery?
The answer is iron. It is used to make steel for tools,machinery,and light-blub filsments. +++ Not the light-bulb filaments. They are made from tungsten.
What do metals and machinery the metal filament in a light bulb and steel girders used to frame an office building all have in common?
all are metals and condutors
What do metal tools an machinery the metal filament in a light bulb and steel girders used to frame an office building have in common?
They began as minerals inside earths crust
What do metal tools and machinery the metal filament in a light bulb and steel girders used to frame an office building all have in common?
They are all made of metal, which is known for its strength and durability. Metal tools and machinery, metal filament in a light bulb, and steel girders used in construction all rely on the properties of metal to serve their respective functions effectively.
What is always in light bulb filaments?
Tungsten is always in light bulb filaments :)
What metal use the filaments in light bulbs?
Tungsten is used in filaments of light bulbs.
What minerals have tools machinery light bulb filaments and steel grinders?
Tools and machinery often incorporate metals like steel, which is primarily made from iron and carbon. Light bulb filaments are commonly made from tungsten, known for its high melting point and durability. Steel grinders may also include various alloys that contain minerals like chromium and nickel to enhance strength and resistance to wear.
What is the difference between heavy and light mineral oil?
Heavy mineral oil is a more viscous substance, light mineral oil is less viscous. Therapeutically, Light Mineral Oil is used as an emollient for the skin, while Heavy Mineral Oil is used as a Cathartic/Laxative for the bowel.
What is the use for tungsten?
Light bulb filaments.
A three -way light bulb has 3 filaments?
A three-way light bulb actually has two brightness levels, not three filaments. It achieves this through a combination of filaments that can be turned on in different combinations to produce different levels of light.
The element used in light bulbs filaments?
Tungsten is the element most commonly used in light bulb filaments due to its high melting point and ability to produce light efficiently when heated.
