Web2 days ago · Specifically, we distinguish between “amorphous solid water” (ASW) made by condensation of water vapor, “hyperquenched glassy water” (HGW) made by rapidly cooling μm-sized liquid droplets, and “low-density amorphous” (LDA) ice prepared from crystalline ice in a high-pressure setup, usually a piston-cylinder setup or a diamond-anvil ... WebMar 29, 2024 · Solids are of two types - Crystalline and Amorphous solids. Crystalline solids are hard and possess a definite geometrical shape. Amorphous solids are soft and do not possess a definite shape. Crystalline solids have a definite melting point whereas amorphous solids do not have a fixed melting point and soften over heating.
