Superconductors with a critical temperature above 77 K are called
Correct answer: B. high temp superconductor
- A. low temp superconductor
- B. high temp superconductor
- C. superconductors do not exist above 77 K
- D. moderate temp superconductor
Explanation
Superconductors with critical temperatures above 77 K are categorized as high-temperature superconductors. These materials can undergo superconductivity at temperatures higher than the boiling point of liquid nitrogen (77 K). Examples include certain ceramic materials like yttrium barium copper oxide (YBCO) and bismuth strontium calcium copper oxide (BSCCO)

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
