Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
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.
mudstone and shale. These can become the metamorphic rock slate if exposed to high pressure and temperature.
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.
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.
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.
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).
they are made from clay that are heated in a high temperature room...
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.
Modern ovens can be set to an exact temperature for instance.
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).
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.
The artificial magnet made by pressing magnetic powder together under high pressure and temperature is called a sintered magnet.
No it is not, because it is made of mostly high temperature gas with incredible heat.
clay after making the statue it'll be heated at high temperature.
It is melted at a very high temperature. Then, it is formed into the desired shape.

I do not know but I know that porcelain is a name for goods made with fine grained clay (kaolin) fired at a high temperature, that is often made into high quality cups and dishes.
