High density ice
Web17 de fev. de 2016 · The planet’s overall density is lower than that of Earth’s, estimated at 3.933 g/cm³, and this density increases the closer one gets to the core. Like Earth, this is due to the fact that the ... Ice VII is a cubic crystalline form of ice. It can be formed from liquid water above 3 GPa (30,000 atmospheres) by lowering its temperature to room temperature, or by decompressing heavy water (D2O) ice VI below 95 K. (Different types of ice, from ice II to ice XVIII, have been created in the laboratory at different temperatures and pressures. Ordinary water ice is known as ice Ih in the Bridg…
