Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.

How do astonomers know corona temperature is so high?

Astronomers know the temperature of the Sun's corona is high because they can observe the emission of extreme ultraviolet and X-ray radiation from the corona, which is only possible if the temperature exceeds millions of degrees Celsius. These observations are made using instruments such as spectrometers and telescopes designed for detecting these high-energy wavelengths.


What type of sedimentary rock is made from compacted mud?

mudstone and shale. These can become the metamorphic rock slate if exposed to high pressure and temperature.


What temperature does glass need to be made?

Glass is typically made from a mixture of silica sand, soda ash, and limestone, which is heated to around 1700°C (3092°F) to melt and form glass. This high temperature allows the ingredients to fuse together and form a molten glass that can be shaped and molded.


What rock is made by temperature and pressure?

Metamorphic rock is formed when existing rocks are subjected to high temperature and pressure, causing them to recrystallize and change their mineral composition without melting. Examples of metamorphic rocks include marble, slate, and schist.


What is the average high and low temperature on Uranus?

The average high temperature on Uranus is around -197 degrees Celsius, while the average low temperature is around -224 degrees Celsius. Uranus is one of the coldest planets in our solar system due to its distance from the Sun and its lack of internal heat sources.

The lowest temperature a superconducter can work at?

0oK, or absolute zero is the lowest temperature. Superconductors have a critical temperature at which they begin to work, but it is the highest temperature, and they function as superconductors at any temperature lower, down to as close to absolute zero as they can be made to be (absolute zero is unachievable).

What are modern thermometers made of?

Modern thermometers are typically made of materials such as glass, plastic, or metal. The most common type of modern thermometer is the digital thermometer, which includes a temperature sensor and a digital display screen. Other types of modern thermometers may contain mercury or alcohol as the temperature-sensitive material.

How ARE superconductors different from solid liquid and gasses?

The question is like asking "what's the difference between a red shirt and one made of nylon"? Superconductors are also solids. I don't think there are any liquid or gaseous superconductors (weird stuff may happen in portions of the phase diagram far removed from ordinary Earthly conditions, so I'm not absolutely positive that, say, liquid metallic hydrogen or whatever isn't superconducting, but any superconductors we can actually make on Earth are solids).


How do you make a superconductor?

To make an yttrium-barium-copper-oxide superconductor, you will need:* Yttrium Oxide* Barium Carbonate (TOXIC)* Cupric Oxide* A Laboratory Furnace or a converted pottery kiln. * Labware made of alumina. * An Oxygen Source* Liquid Nitrogen and a rare-earth magnet for testing and demonstrating the superconductors. Method:There are a number of methods of producing ceramic superconductors like this, but the simplest is the so-called â??shake and bakeâ?? method, which involves a four step process:1. Mixing the chemicals;2. Calcination(the initial firing);3. The intermediate firing(s) (oxygen annealings);4. The final oxygen annealing.
