Polyamorphism in Water and the Second Critical Point Hypothesis

Liquid water shows the eccentric properties at low temperatures such as the maximum density at 4℃. The amorphous solid form of water also shows a peculiar phenomenon known as polyamorphism. Poole et al. has proposed the second-critical-point hypothesis of water and explained these properties. The experimental and theoretical studies support the hypothesis, but further proofs are required.
