Question

Second order phase transition is
defined as :
(A) Discontinuity in first order
derivative of Gibbs free energy
(B)
Continuity in second order
derivative of Gibbs free energy
(C) Discontinuity in second order
derivative of Gibbs free energy
(D)
None of these​

Answer 1

Answer:

Second-order phase transitions are also called "continuous phase transitions". They are characterized by a divergent susceptibility, an infinite correlation length, and a power law decay of correlations near criticality. So the answer is option (c).
