The question is coming because for the two phase transitions, one is characterized by sharp changes in enthalpy & the other stays as a diffused broad change (e.g., glass transition). Is it also possible that such phenomena are strongly material dependent? I mean, the same melting or glass transition would show exceptional changes in enthalpy as one changes the system of materials. Please send me some relevant research papers or book references on this topic.
Dear Lakshaman Kumar, you Can not take the amount of energy as as a parameter to differentiate between them, though 1st order give/take much energy compared to 2nd order. It is a matter of type of energy and way of change/relaxation. Please read carefully the text presented in the link below. My Regards

Indeed, the glass transition, which has been thought as somehow resembling a second order phase transition in terms of the Ehrenfest classification, even if this analogy is based at idealized circumstances that can not be realized in practice ― you may check: Article Aspects of the non-crystalline state
In general, the transition of the first order has a temperature hysteresis (heating-cooling). The second-order transition has no hysteresis. All this can be determined from the DSC curves.
Dear All,
Thank you for your tips and suggestions. These comments are eyes opening for me and helped me to understand my finding more accurately.
Thanks and Regards
Lakshaman Kumar
