What conditions are necessary for materials to become a superconductors?
Materials need to be cooled below a certain temperature called the critical temperature, at which they undergo a transition from a normal conductor to a superconductor. They also need to be in a state of superconductivity, where they exhibit zero electrical resistance and expel magnetic fields. Additionally, the material's crystal structure and electron pairing mechanism play a role in determining its superconducting properties.
Do balloons have electricity?
Balloons themselves do not generate electricity. However, they can become charged with static electricity when rubbed against certain materials or in certain environmental conditions. This static charge can cause the balloon to stick to surfaces or attract small objects.
What kind of materials can become electrically charged when they are rubbed together?
When certain materials are rubbed together, they can become electrically charged. These materials are typically non-metallic and include substances like rubber, plastic, and fur.
What do some electrical conductors become when cooled to near absolute zero?
Some electrical conductors become superconductors when cooled to near absolute zero. This means they can conduct electricity with zero resistance, allowing for efficient electrical transmission and various technological applications.
What materials can be charged with static electricity?
Materials that commonly become charged with static electricity include plastics, rubber, glass, and certain fabrics like polyester and wool. These materials tend to acquire a static charge when rubbed against each other or when exposed to friction or low humidity conditions.
Under what conditions do certain materials become superconductors?
Low temperature is a factor to increase electrical conductivty.
Certain material can become superconductors under what conditions?
when it is very cold(:

Why superconductors are not used often in everyday activities?
Because at present all superconductors must be super-cooled in a coolant such as liquid nitrogen to become superconductors.
Does an insulator become a superconducter at absolute zero?
No, only certain materials can become superconductors. These materials form Cooper Pairs with their conduction band electrons at low temperature, making the electrons coherent (analogous to photons in a LASER beam). This coherence prevents resistance to current flow. Most insulators lack conduction band electrons. High temperature copper oxide ceramic superconductors are an exception as they lack conduction band electrons, but their copper oxide structure is highly distorted in a way that allows bound electrons to form Cooper Pairs.
Is a superconductor a metal or nonmetal?
Only a few of the materials that have been supercooled have become superconductors, and not all of those are metals. There have even been some organic superconductors discovered.

Does the coldness affect the minerals hardness?
Many materials become more brittle in cold conditions.
