Question

The temperature below which a material becomes a superconductor is called
(A) Critical temperature
(B) Absolute temperature
(C) Triple point
(D) None of the above

Answer 1

Hint : To get the answer and to complete the given statement, refer all the given terms and then will find out the correct option. Know the different types of temperatures and its applicable properties. Temperature can be defined as the physical quantity which expresses the hotness and the coldness.

Complete Step By Step Answer:
Critical temperature can be defined as the temperature below which the taken metals exhibits zero resistivity and which ultimately turns into the superconductor. The critical temperature varies directly with the individual material because these materials have no electrical resistance which means that the electrons can travel freely through them and they can carry large amounts of electricity being good conductors of electricity and therefore carries electricity for long periods of time without losing energy as the heat. This transition is so sudden which completes and appears to be the transition to the different phase of matter which is known as the superconducting phase.
From the given multiple choices, the option A is the correct answer.

Note :
Know the difference between the types of temperatures. Absolute temperature is also known as the thermodynamic temperature and the temperature of an object on the reading scale where zero is taken as the absolute zero. The triple point of the substance can be defined as the temperature and the pressure at which all the three phases i.e gas, liquid and solid substances co-exists in the atmosphere.
