High density ice
WebThe structural nature of high-density amorphous ice (HDA), which forms through low-temperature pressure-induced amorphization of the “ordinary” ice I, is heavily debated. Clarifying this question is important for understanding not only the complex condensed states of H2O but also in the wider context of pressure-induced amorphization … Web15. an ice cube floats in a glass of water filled to brim. what can you say about the density of the ice? as the ice melts will the water overflow?
