I found somewhere that in 1st order phase transition , at the transition temperature , specific heat of the system diverges. Can anyone explain me why and how ?

Take the example of ice-water system in its melting point(equilibrium). If you add heat to the system the temperature will not rise(only some more of the ice will melt).

The specific heat is change in heat($\delta$Q) per unit change in temperature($ \delta$T) but $\delta$T is zero here so specific heat tends to infinity.
