We analyze the heat capacity CP for low and high-density amorphous ice below the transition temperature (TC ≈ 140 K ) using a power-law formula. The renormalized critical exponent αR is extracted from the observed CP data, which describes similar critical behavior for both low and high-density amorphous ice below TC. Our analysis can also describe a glass transition in the low-density amorphous ice which is made from the high-density amorphous ice at 124 K, as observed experimentally.
