  We study explosive percolation (EP) on Erd\"{o}s-R\'{e}nyi network for
product rule (PR) and sum rule (SR). Initially, it was claimed that EP
describes discontinuous phase transition, now it is well-accepted as a
probabilistic model for thermal continuous phase transition (CPT). However, no
model for CPT is complete unless we know how to relate its observable
quantities with those of thermal CPT. To this end, we define entropy, specific
heat, re-define susceptibility and show that they behave exactly like their
thermal counterparts. We obtain the critical exponents $\nu, \alpha, \beta$ and
$\gamma$ numerically and find that both PR and SR belong to the same
universality class and they obey the Rushbrooke inequality.
