  4. The temperature at which it becomes a normal conductor

Questions & Step-by-Step Solutions

What is the critical temperature for a superconductor?
Correct Answer: Critical temperature is the temperature below which superconductivity occurs.
  • Step 1: Understand what superconductivity means. It is a state where a material can conduct electricity without any resistance.
  • Step 2: Learn about temperature. Temperature is a measure of how hot or cold something is.
  • Step 3: Know that every material has a specific temperature at which it can become a superconductor.
  • Step 4: This specific temperature is called the critical temperature.
  • Step 5: Below the critical temperature, the material will show superconductivity and lose all electrical resistance.
