9.2.7.1 Basic Definitions Critical temperature (T c)The maximum temperature at which a gas can be converted into a liquid by an increase inpressure. Critical pressure (p c)The minimum pressure which would suffice to liquefy a substance at its criticaltemperature. Above the critical pressure, increasing the temperature will not cause a fluidto vaporize to give a two-phase system.
Determination of the Critical Temperature. The Critical Temperature (Tc) is obtained during the measurement of the electrical resistance as function of the Temperature of the superconductor above. The Critical Temperature of the Bi2Sr2Ca2Cu3O10 superconductor is about 108 Kelvin versus about 95 Kelvin for the YBa2Cu3O7 material.
