For a microscope to be useful it must combine two properties?
it must combine magnification and resolution
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 is the function of quartz?
Quartz is a natural substance, SiO2, and has a number of properties useful to us. It has a high melting point compared to ordinary glass, it has some very useful piezoelectric properties, It has a high propensity to crystallize when in compound with other substances. Hence many of our precious jewels.
Both steel and chalk are solids What properties of steel make it more useful than chalk for building bridges?
the steel has stronger force between its atoms compared to chalk
Name two physical properties of nonmetals?
Well, nonmetals are opaque and brittle. They are also bad conductors of heat and electricity.
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.
Acids give soaps their useful properties?
Nope, bases actually gives soaps their useful properties.
What are some uses for tungsten?
Tungsten is useful for glass-to-metal seals since the thermal expansion is about the same as borosilicate glass tungsten and its alloys are used extensively for filaments for electric lamps, electron and television tubes, and for metal evaporation work electrical contact points for car distributors X-ray targets windings and heating elements for electrical furnaces missile and high-temperature applications high-speed tool steels and many other alloys contain tungsten the carbide is important to the metal-working, mining, and petroleum industries calcium and magnesium tungstates are widely used in fluorescent lighting tungsten salts are used in the chemical and tanning industries tungsten disulphide is a dry, high-temperature lubricant, stable to 500°C tungsten bronze and other tungsten compounds are used in paints TV tubes (electron tubes) Nozzles for the rockets engines, for example, are made from tungsten steel.
What makes a substance a special kind of stuff?
Substances become special because they have useful properties. Tungsten has an extremely high melting point, which makes it useful as a filament in incandescent light bulbs. Oxygen supports combustion and metabolism. Glass is valued for being transparent as well as waterproof, strong, and durable. And so forth.
